Error Code 0x8024001b- What is it?

At its most basic level, Error Code 0x8024001b is an error that can cause problems with the installation and updates of software and operating system updates. The most common version of this error appears in Windows 10, but a similar error with a matching code number has been present in previous versions of the operating system, back through Windows 7.

Common symptoms include:

• Programs freezing or locking up during use
• The appearance of an error message regarding installation difficulties
• Computer shutting down or freezing during operation
• Difficulty in running multiple programs at the same time

Solution

Error Causes

There are two main causes for Error Code 0x8024001b, both of which are fairly simple:  Updates needed for the Windows Update tool itself and software that causes Windows Update to fail during installations through conflicts in system files. While these may seem like technical issues, these problems are actually easily resolved with a few simple steps. The average user can use the methods listed below to fix the problems on their own.

Further Information and Manual Repair

For users who want to address Error Code 0x8024001b for themselves, the steps below can be followed to address the two primary causes for the error. If you have difficulty in completing these steps or are not confident in your computing skills and ability to follow the listed steps, contact a Windows repair technician.

Here are the top methods to resolve Error Code 0x8024001b on your own:

Method One:  Check for Updates to Windows Update

In some cases, the Windows Update tool may need an update for itself. When you attempt to run updates or install wizards for other software, it can cause conflicts with the Windows Update process, slowing down your computer or causing it to freeze.

If you are attempting to run multiple installations or updates at the same time, it may also cause Error Code 0x8024001b to arise on your computer.

To resolve this issue, close out all programs, with the exception of the Windows Update tool. Within the tool, select “Check for Updates” and install any updates that are needed. When finished, you should restart your computer to ensure that all updates have been fully applied before attempting any other installations or updates.

Method Two:  Uninstall Conflicting Software

Another problem that can cause Error Code 0x8024001b is the presence of conflicting software. If Error Code 0x8024001b has only recently appeared on your computer, consider removing any software that has been added to your computer, running the Windows Update process, and restarting your computer before attempting to reinstall the problem software.

With any method that you use, it is important to remember to keep your Windows Updates current at all times. This is the best way to avoid the appearance of Error Code 0x8024001b and similar errors in the future, as stacked up updates are more likely to cause issues and conflicts with your other installed software and operating system.

While there are some tools out there that claim to be able to fix Error Code 0x8024001b for you, it is important to always thoroughly investigate the publisher and distributor of such software, as some of the tools available on the Internet will actually introduce malware and adware on your computer in the name of “protecting” your computer or resolving an error.

If you have tried to use both methods above and have not fully resolved Error Code 0x8024001b, get in touch with someone who is a qualified computer repair professional and is familiar with your particular version of the Windows operating system to assist you in finalizing your resolution.

Method Three: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

After so many years World of Warcraft is still among the most played MMORPG games in the world. It is still constantly updated with new content and tweak graphically in order to be relevant and fresh. But even the best or most popular ones can still have some minor issues and bugs from time to time. CAS System Was Unable to Initialize is the error that was reported lately by WOW players all around the globe and it happens in multiple Windows systems. In this guide, we will take with this issue and provide you with solutions on how to fix it so you can get back to enjoying the game itself.

1. 1. Repair WOW

      In battle.NET launcher select WOW and click on Options Click on Scan and Repair Let the process finish and then launch the game again

   2. Clean Windows registry

      Windows cleaning registry operation is a complex task and we will not cover each possible scenario here, instead of trying manually to find issues and clean registry download and install third party registry cleaner software.

   3. Run WOW with command line argument

      One of the solutions for this particular error is to run WOW with a specific command line switch: Run battle.NET client as administrator by right-clicking on it and choosing run as administrator If you are not signed in, sign in now Click on World of Warcraft to select it Click on options Click on Game settings Check the box associated with Additional command-line arguments When the box is selected you should've able to add inline argument or switch, add -uid wow_engb and confirm Run World of Warcraft

   6. Remove read-only attribute from WoW folder

      Another reason for CAS System Was Unable to Initialize error is because the World of Warcraft folder has been set to read-only and since the client does not have write privileges it will throw this error. To remove the read-only attribute from the folder go to your World of Warcraft installation folder but do not enter it Right-click on it instead and choose properties Under properties uncheck the read-only box and confirm. Run World of Warcraft

As you know, each time you log out of your Windows 10 computer, it will take you to the login screen where you can switch users or log back in. But there are instances where Windows 10 remains stuck on the signing out screen, along with a blue spinning circle and all you can see is the process of your computer signing out, however, it does not progress and only gets stuck there. Thus, in this post, you will be guided on how you can resolve such an issue on your Windows 10 computer. So if you are one of the users who experience the same problem, there are several fixes you can check out if your computer is stuck on the signing out screen with a blue spinning circle. You can try to force shutdown your computer or troubleshoot the problem in a Clean Boot State. You could also try to check the status of the User Profile Service or repair User Profile, as well as run System Restore. For more details, refer to each one of the suggestions provided below. But before you troubleshoot the problem, make sure that you are logged in to your computer as an administrator.

Option 1 – Try to force shutdown your computer

The first thing you can do is to force reboot your computer as this simple fix could help in fixing the problem. This option is quite simple, just make sure that before you do it, you have to save all your work.

• First, turn on your computer and press and hold the power button for at least 30 seconds. You might notice the screen flashing or making any changes, just ignore it.
• After that, plug out and plug in your computer and automatically turn it on.
• Once done, check if the issue is now fixed or not.

Option 2 – Put your computer in a Clean Boot State

It is possible that some third-party application is causing your computer to get stuck in the signing out screen. So you can try putting your computer in a Clean Boot State and see if it fixes the problem.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” checkbox.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Once your computer is in a Clean Boot State, you should now be able to sign out or sign in without any problem.

Option 3 – Try checking the status of the User Profile Service

If forcing your computer to shut down or putting your computer in a Clean Boot State didn’t fix the problem, you can try to check the status of the User Profile Service since it is the one responsible for loading and unloading user profiles. Thus, if this service is disabled or stopped, you will no longer be able to sign out or sign in successfully.

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Services Manager.
• From there, look for the User Profile Service and make sure that its Startup Type is set to Automatic and that its status is “Started”.
• Once done, exit the Services Manager and see if the issue is resolved.

Option 4 – Try to repair your corrupted profile via Registry

In this second option, you can try to repair the corrupted profile using the Registry but before you proceed, make sure to create a System Restore Point and then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “regedit” in the field and hit Enter or click OK to open the Registry Editor.
• Next, go to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList
• Once you’ve opened the registry key, you should see a list of all the user profiles on your computer. Now click on each S-1-5 folder and look for the “ProfileImagePath” entry and double click on it to check which user account it is related to. You will see a path like “CUsersACK” where “ACK” is the username.
• You should know which of the user account is corrupted. Just look for a key named “RefCount” and change its Value data to “0” and click OK. And if it isn’t available, simply right-click on the right pane and create it.
• After that, double click on the key named “State” and make sure that the Value data is “0” and click OK.
• Exit the Registry Editor and restart your computer to apply the changes made and then check if it fixed the problem or not.

Option 5 – Run System Restore

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

FLoC is Google’s alternative to third-party cookies and is based on machine learning. This will allow the browser, any browser, to anonymously study how users are browsing and then group them into ‘cohorts’. Following this, you will be served ads based on your cohort and not on your individual data. So, you are still going to be targeted with ads but in a more anonymous manner. Google claims that this will improve user privacy since this “federated learning” happens on the user’s device and artificial intelligence-based learning involves sharing lesser users than what happens with third-party cookies. If something like this gets widely adopted by ad companies and services, it should “protect users” from tracking methods that are more intrusive than third-party cookies, like browser fingerprinting.

Who is against it?

Privacy-focused browsers DuckDuckGo, Brave, and Vivaldi have all warned users against FLoC and have said that they are going to block it on their end. Brave says that Google FLoC has a design that does not respect the customer’s privacy and consent. It has been designed to provide browsing behavior and interest data with any website that users may interact with, and this process does not involve fully informed consent. Vivaldi, another popular Chromium-based web browser, has also made its stance clear regarding the status of FLoC. The company said in a Reddit thread that the FLoC experiment does not work in Vivaldi. It happens because for FLoC to work, some features need to be enabled under the hood, but Vivaldi does not provide those options. The company also added that it plans to stop the entire FLoC component from being a part of the browser, regardless of how Google may implement it. Considering that Brave and Vivaldi have been privacy-focused browsers since their beginnings, the decision to stay away from FLoC is not surprising.

The MP4 MIME-type is a video type that is mainly configured in IIS or Internet Information console. It is the one that instructs a web browser to use the default video application when running MP4 files from websites. MIME which stands for Multipurpose Internet Mail Extensions which offers a way to identify files on the Internet-based on their format and nature. For example, when a content-type header value like MP4 is defined in an HTTP response, the browser can be configured to open the file with the proper plugin. However, there are some servers that don’t have an associated MIME type to support MP4 files and so they fail to play these files. In such cases, you will encounter the “Unsupported video type or invalid file path” error, especially when you use the Internet Explorer browser in Windows 10. To fix this problem, you may have to configure the MP4 MIME type in IIS but you might find that IIS is not enabled in Windows 10 which is why you need to turn it on or enable it first. For more details, refer to the following instructions below.

Step 1 – Enable IIS:

• Open Control Panel and go to Programs > Programs and Features.
• From there, select “Turn Windows features on or off” to mark its checkbox.
• After that, select “Web Management Tools” and expand its menu and look for “IIS Management Console”.
• Click the OK button and then wait for a couple of seconds to allow Windows to successfully apply the changes made.

Step 2 – Configure the MP4 MIME type in IIS:

• Go to Control Panel and from there, access Administrative Tools.
• Next, click “Internet Information Services Manager” from the list of given options.
• Once confirmed, it will open the IIS console where you have to click the name of your IIS Server located on the left panel. This will enable several options in the central details section.
• Now double click on the icon with the label “MIME Types”.
• After that, you should see an “Add” link option on the right panel. Click on the link to open a configuration dialog box.
• Then type “.mp4” in the File Name Extension field and enter “video/mp4” in the textbox of the MIME Type.
• Click the OK button to save the changes made. This should fix the “Unsupported video type or invalid file path” error on your Windows 10 computer.

Step 3 – Reset your browsers:

Mozilla Firefox

• Open Firefox and click the icon that looks like three stacked lines located at the top-right section of the browser.
• Next, select the question mark icon from the drop-down menu.
• Then select “Troubleshooting information” from the slide-out menu.
• After that, click on the “Reset Firefox” button located at the top-right section of the newly opened web page.
• Now select “Reset Firefox” in the confirmation pop-up window that appears.

Google Chrome

• Open Google Chrome, then tap the Alt + F keys.
• After that, click on Settings.
• Next, scroll down until you see the Advanced option, once you see it, click on it.
• After clicking the Advanced option, go to the “Restore and clean up option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
• Now restart Google Chrome.

Internet Explorer

• Launch Internet Explorer.
• Next, click the wrench icon for Settings.

If you are trying to open a program or a game but you suddenly see a dialog box with a message stating that the application was unable to start correctly along with the Error Code 0xC000007B , STATUS INVALID IMAGE FORMAT then this indicates that the application is not compatible with the architecture of your Windows 10 computer or is missing dependencies. Although error code 0xC000007B can also occur with other various programs, the STATUS_INVALID_IMAGE_FORMAT error code also means that when you try to run an application that’s designed to run on a 64-bit system and hence gets into a termination state. In addition, if you are also pointed to the NTStatus.h file then it means that the error might be caused by some file corruption. Here’s the full context of the error message:

“0xC000007B | STATUS_INVALID_IMAGE_FORMAT | {Bad Image} %hs is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.”

When you see this error message, the first thing you can do is to click on OK to close the application and then try installing the media again to see if it fixes the issue. If not, then you can check out the suggestions given below.

Option 1 – Try installing the application with admin privileges

The first thing you can do to fix the error is to restart your Windows 10 computer and then try installing the application again and this time with admin privileges. Just right-click on the application and select the “Run as Administrator” option. And if your account is a regular one, you need to make sure to ask an admin to help you in installing the application by entering the password when you are prompted to do so.

Option 2 – Install and update Dependencies

There are times when programs and applications need to have drivers and supporting software installed for them to properly work. Although the installation usually takes care of it, it’s time for you to do some manual checks especially if you are getting this issue of abnormal program termination.

1. Install some qualified drivers

A number of high-end games and applications need to have correct and valid drivers for them to work. They just don’t work with general drivers though. Microsoft has this Windows Hardware Quality Labs testing also known as WHQL testing which makes sure that drivers meet the correct experience and pass through the proper testing before certification. Thus, when installing drivers, you need to ensure that they are qualified drivers for your Windows 10 PC.

2. Download and install or update DirectX

As you know, Microsoft DirectX is a suite of technologies developed by Microsoft to provide hardware acceleration for heavy multimedia applications like HD videos and 3D games. Since you are using Windows 10, you have the DirectX 12 version while the earlier Windows versions use the DirectX 11 version.

3. Install the Microsoft DirectX End-user runtime

The Microsoft DirectX end-user runtime gives updates to version 9.0c as well as previous versions of DirectX. To install it, click on this link and download it.

4. Update or install the .NET framework

The .NET framework is used by games and applications during development which means that without the runtime files that are installed in your computer, it definitely won’t work. Thus, you need to install or update this framework. You can also use the .NET setup verification tool to verify it.

Option 3 – Try running the System File Checker Scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Error Code 0xC000007B , STATUS INVALID IMAGE FORMAT error. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

As you know, every Windows Update is essential for every Windows operating system. They have to be regularly installed, especially since they include various security updates that are important to the system. However, there are times when Windows Update fails to execute properly and you get errors like the error code 0x80070BC9. When you encounter this particular Windows Update error, you will get the following error message on your screen:

“0x80070BC9 – ERROR_FAIL_REBOOT_REQUIRED. The requested operation failed. A system reboot is required to roll back changes made.”

This kind of Windows Update error is most likely caused by a newly installed problematic software, corrupted Windows Update files, or policies that restrict the behavior of the Windows Module Installer. The Windows Module Installer, also known as “WMIW” or “TiWorker.exe”, is the one that checks for new updates from the Windows server and installs them on your computer. This is why you need to make sure that you do not have any policies that control the start behavior of the Windows Module Installer since this service must not be hardened to any start value and should be managed by the operating system. To resolve the Windows Update error code 0x80070BC9, you can check out the options provided below.

Option 1 – Try checking the status of the Windows Modules Installer Worker Service

Since the Windows Update error code 0x80070BC9 has something to do with the Windows Module Installer Worker service, you need to check its status in the Service Manager. Refer to the following steps to do so.

• In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “MSC” in the field and hit Enter to open the Services Manager.
• After opening the Services Manager, look for the Windows Modules Installer Worker Service.
• Once you found it, check its status and make sure that its Startup type is set to Manual.
• Now click on the Start button and see if it fixes the Windows Update error.

Option 2 – Run the Windows Update Troubleshooter

You might want to run a built-in Windows Update troubleshooter to resolve the Windows Update error. It is one of the things you can check out as it is known to automatically resolve any Windows Update errors like error code 0x80072EE2. To run this troubleshooter, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 3 – Try contacting the IT administrator to modify the group policies

You could also try to contact the IT administrator to have the group policies modified. This option is applicable for company-managed systems. As mentioned, one of the possible causes of the Windows Update error 0x80072EE2 is the policies that control the start behavior of the Windows Module Installer. Thus, you need to have them removed so that the Windows Module Installer Worker service is managed by the operating system itself. And since there could be many policies, it is highly advised that you contact your company’s IT administrator to get the job done for you.

Option 4 – Try to install the Windows Updates in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing Windows Update error code 0x80070BC9. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

One of the great remote assistance software that helps you remotely access and control computers is TeamViewer. However, despite how efficient it is, there are still times when it throws up some errors and one of them is when TeamViewer is not able to connect and throws an error that says, “No connection to partner, Partner did not connect to router, Error Code WaitforConnectFailed”. This kind of error in TeamViewer mostly occurs when the Partner computer is not connected to a network. On the other hand, it could also occur when they are connected to a network so there are various causes for this issue. It could also be that the installation of the program itself was at fault or there is an incompatibility between the TeamViewer versions installed on both the computers and so on. Although there are several causes for this error, the potential fixes are still the same. You can try to restart the network or allow Full Access Control to TeamViewer or flush the DNS cache. For more information, refer to the following options but before you proceed, make sure that both your Windows 10 computer and TeamViewer program are updated to their latest stable versions.

Option 1 – Reboot your router

The first thing you can try to do to fix the error is to simply restart your router. All you need to do is reboot the router from its Admin panel or you can also turn it off manually and turn it back on after a couple of seconds so that it can completely reboot. Once you’re done, try accessing your server again and see if the error is now fixed.

Option 2 – Allow Full Access Control to TeamViewer

• First, open TeamViewer, and then from the Menu bar, click on Extras.
• After that, click on Options and select Advanced from the left side navigation panel.
• Next, click on the “Show advanced options” button located on the right-hand side.

• After opening Command Prompt with admin privileges, enter each one of the commands given below sequentially in order to flush the DNS cache.
  • ipconfig/release
  • ipconfig/renew
  • ipconfig/flushdns
• Now type the exit command to close Command Prompt and then restart your computer and see if the problem is fixed.

On the other hand, you could also try to reset Winsock as well as the TCP/IP.

Option 4 – Run the Network Adapter troubleshooter

To run the Network Troubleshooter, refer to these steps:

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.

If you are running Windows Update on your Windows 10 computer and you suddenly encounter error code 0x8000FFFF, E_UNEXPECTED – Unexpected failure then read on as this post will give you a couple of suggestions to resolve this problem. Note that you can encounter this error not only on Windows Update but also on Microsoft Store apps at times. Follow the options given below to fix error code 0x8000FFFF, E_UNEXPECTED – Unexpected failure error on your Windows 10 PC.

Option 1 – Try to reset the Microsoft Store cache

Just like browsers, Microsoft Store also caches as you view apps and games so it is most likely that the cache is no longer valid and must be removed. To do so, follow the steps below.

• Right-click on the start button and click on Command Prompt (administrator).
• Next, type in the command, “wsreset.exe” and tap Enter. Once you do, the command will clear the cache for the Windows Store app.
• Now restart your PC and afterward, try opening Microsoft Store again.

Option 2 – Check the Cryptographic Service

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter or click OK to open Services.
• From the list of Services, look for the Cryptographic Service. Then right-click on it and select Properties from the context menu.
• After that, check if the service is started by checking the Service status. If it is started, click on the Stop button to stop the service and if it is already stopped, leave it as it is, at least for now.
• Next, make sure that the Startup type menu in the Service’s properties is set to Automatic before you go on.
• Now confirm any dialog boxes that may appear as you set the Startup type and then click on the Start button located in the middle before you exit Properties.

Option 3 – Delete the contents in the Software Distribution folder and Catroot2 folder

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

Option 4 – Check the Root Permissions

You might also want to check the permissions on the root of C: and make sure that “BUILTINUsers have read access because if it doesn’t, then no wonder why you’re getting the error code 0x8000FFFF.

Option 5 – Try to use the Media Creation tool

The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

• After making the bootable drive, you need to plug it into your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

Option 6 – Try installing the updates in a Clean Boot State

It could be that some third-party application is the one that’s causing the problem so it’s best if you put your computer in a Clean Boot state. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” checkbox.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After that, try to install the Windows app again.

Note: If you are able to install the app without any trouble at all then it means that the error is caused by some third-party application in your computer. You need to look for the culprit and uninstall it once you found it.
