“CoreFoundation.dll was not found” or “Apple Application Support is missing’.

Solution

Error Causes

The CoreFoundation.dll error message is triggered because of several reasons. These include:

• Deleted CoreFoundation dll file
• The CoreFoundation dll file has been overwritten
• Poor installation of the Apple software
• Corrupt software due to viral infection
• Registry problems

Further Information and Manual Repair

It is advisable to fix CoreFoundation dll error code right away to avoid inconvenience. This error may stop you from accessing and running your desired Apple application. Here are some of the best ways to resolve this error on your system:

1. Restore the Deleted CoreFoundation dll File

Since Dynamic Link Library is a shared program, if you happen to delete an Apple program on your PC, chances are you might have deleted that file too in the process. Therefore, the easiest way to recover and restore the CoreFoundation dll file and resolve the error is to look for the file in the recycle bin. If you can’t locate it, then another way to restore the missing CoreFoundation dll file is to download the files from the internet.

2. Reinstall  Apple Software

If the error still persists then it is advisable to re-install Apple software via iTunes or any other Apple Software that you have on your PC. For example, if you have iTunes, then to reinstall it first go to the start menu and then the control panel. Now click on Add/Remove programs and locate iTunes software. Click the Uninstall button next to iTunes. Wait for a while until the program is completely uninstalled. After the installation is complete, restart your PC and then download the latest version on iTunes and install it. Now try running the software again. Hopefully, this will resolve the issue.

3. Scan for Viruses

Another way to resolve CoreFoundation dll error on your system is to scan for viruses. Run an antivirus to detect viruses and remove them from your PC.

One of the most useful and efficient command-line disk management tools is the DISKPART utility. It can be used to manage, delete or create new hard drive partitions. However, despite its efficiency, there are still times it could face some errors like the “No usable free extent could be found”. You can encounter this error when you create a partition. This error could be due to insufficient disk space which is why it is not able to carry out the operation. It is also possible that the disk is not recognized by the system. And since there are only four recognized primary partitions, when you try creating a fifth one, you will get this error. In addition, this error could also occur if the disk has been partitioned using the MBR disk partitioning format. To fix the “No usable free extent could be found” error, here are some suggestions you can follow.

Option 1 – Free up disk space using Storage Sense

The error could be caused by insufficient disk space in your computer and so you need to free up disk space using Storage Sense to fix the problem.

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
• Next, find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
  • Windows Upgrade Log Files
  • The system created Windows Error Reporting Files
  • Thumbnails
  • Temporary Internet Files
  • Previous Windows Installation Files
  • Delivery Optimisation Files
  • DirectX Shader Cache
• Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
• Now go to the “Free Up Space Now” section and click the Clear Now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix Error 1310.

Note: You can also run the Disk Cleanup tool to free up disk space.

Option 2 – Try to run DISKPART in Command Prompt with administrator permissions

The next thing you can do to resolve the error is to run the DISKPART utility with admin privileges.

• In the Start Search, type “command prompt” and from the search results that appear, look for Command Prompt.
• Once you found it, right-click on it and select the “Run as administrator” option.
• After that, try to execute the Diskpart operation once again. Note that you also have to specify different size & offset values for the partitioning and then see if you still encounter the same error.

Option 3 – Try to execute the DISKPART clean command

The next thing you can try is to execute the clean command in DISKPART to fix any issues in the disk.

• Open Command Prompt with admin privileges.
• Then execute this command: diskpart
• The command you entered will initiate the DISKPART utility. Now execute this second command to view all the disk connects or all the partitions on those disks formed: list disk
• After that, you need to select one command depending on the list command you executed and then execute this third command: select disk #
• The third command you just executed will select the disk or partition you want to select. Now execute this fourth command: clean
• The command you entered will remove all the volumes or partitions formatting the disk in focus.
• Once it’s done, try to carry out the DISKPART operation you were trying to execute.

Option 4 – Try to update the USB drivers

Outdated USB drivers can also be the reason why you’re getting the error. Thus, you must update them from time to time. You can install the latest version of the USB driver for your system. But you need to check the manufacturer’s website or guidelines to update the driver according to your system. If it happens that the drivers might not be compatible with the version of the system your laptop is using which is unlikely, you can run the driver software in Compatibility Mode in that kind of situation. To update your USB drivers, follow these steps:

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, look for the USB Serial Bus controllers from the list of device drivers displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.

Option 5 – Run the Hardware and Devices troubleshooter or the USB troubleshooter

You can find the Hardware and Devices troubleshooter under the Troubleshooters section of the Windows Settings panel on your Windows 10 PC. You can use this troubleshooter to fix common hardware and external device-related issues without exerting too much effort. If you don’t know where to find it, follow these steps:

• Tap the Win + I keys to open the Windows Settings.

As you know, the USB security keys are a secure medium to validate a lot of components in a computer. They can be used to log in to Windows 10. Now with the advancement of APIs, you can authenticate across the website as well using the same key. However, there are times when it may not work and it could be caused by several factors. It could be due to corrupted or incompatible drivers or it could also be due to compromised integrity of the key, and many more. So if you happen to encounter an issue with the USB security key on your Windows 10 computer, then there are several potential fixes you can try. You can try toggling the Internet Options settings or reinstall the respective USB drivers. You could also try changing the PIN of the security key or disable the antivirus program on your computer or troubleshoot the web browser. Refer to the potential fixes provided below to fix the problem.

Option 1 – Try to toggle the settings of the Internet Options

• In the Windows Search box, search for Internet Options to open it.
• Next, go to the Security tab and drag the security slider to the lowest possible security for all the given zones.
• After that, click on OK to save the changes made and close the Internet Options.

Note that this option is only a temporary measure as it can make your computer vulnerable. Make sure to press the Reset all zones to default level button.

Option 2 – Try to update or reinstall the respective drivers

If updating the drivers of the device did not fix the problem with the USB security key, you can try to update or reinstall the Universal Serial Bus Controller drivers instead of using the Device Manager. Refer to the following steps:

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.

Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.

• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 3 – Try to change the PIN of the security key

If the first two options didn’t work, you can try changing the PIN of the security key. There are instances when the PIN for the security key might have been corrupted. Thus, resetting it can help you resolve the problem.

Option 4 – Temporarily disable Firewall and third-party antivirus

Firewall and antivirus programs are known to block the proper functioning of the USB security key. Thus, your antivirus or firewall programs might be the reason why you can’t download anything on your Windows 10 computer. To isolate the issue, you need to temporarily disable both the Firewall and antivirus programs and then check if you can now download anything from the internet. Do not forget to enable them again as disabling them can leave your computer vulnerable to cyber threats.

Option 5 – Try to troubleshoot the web browser

Troubleshooting your web browser can also help you fix the USB security key problem. You can do that by checking if your web browser supports the security key and you can do that by checking on the official website of your browser. You can also try to update your web browser to its latest version but if it didn’t help, you can try to reinstall it or switch to another web browser.

Having an eMail in today's modern world is no longer a privilege or being geeky, it has surely become a necessity. From Facebook to LinkedIn or Steam many services today require you to have an account in order to use them, and in order to create an account, you need working eMail. That being said many people today have several eMail accounts, one for social media, one for work, maybe even one for very close friends and family. How creating eMail today is completely free we might end up with several eMail accounts. eMail clients have also evolved much since their first days and became more than just applications for receiving eMails, today they can take various different tasks having additional features built into them like calendar, batch eMail processing, etc. Taking all of said into account I am presenting to you within my personal opinion some of the best eMail clients starting with free ones.

Best free eMail clients

Google Gmail

https://gmail.com It would be very difficult to even start a free eMail list without mentioning Google's Gmail. Introduced all the way back in 2004 as an invite-only service it became over time the most popular email platform largely due to the fact Google is offering free eMail accounts. There are a lot of good things to be said about Gmail itself, most of the area is clutter-free and the largest space is reserved for eMail itself letting users focus on what is important. WEB client itself means that you do not need to have any application installed on your device, altho via Google chrome, you can use Gmail offline offering you flexibility if needed. The ability to connect and manage other accounts like Outlook, Yahoo, etc is just making Gmail even more attractive, and the snooze feature is a really neat little detail that will pause eMail notifications if you need to focus on other things. Lack of organizing messages into folders is a little confusing since Gmail offers its own unique label system but sometimes I need to have old reliable save eMail to folder. All in all, Gmail is a great service and it offers a great eMail on the go experience.

Mail eMail client

https://www.microsoft.com/en-us/p/mail-and-calendar/ Free Windows eMail client simply called Mail is what was once outlook express. Mail itself has the ability to work with other popular accounts like Google Gmail account, Yahoo, iCloud etc. How it comes with Windows OS and it integrates very well with Microsoft Calendar, this eMail client is for many the first choice. On the negative side, I might say this is a strip-down version of Outlook which is paid solution so some features are missing if we would compare the two. Overall, a simple and nice eMail client worth your time, especially if you are on the Windows platform.

Mozilla Thunderbird

https://www.thunderbird.net Great eMail client matching in functions against paid and premium solutions of big tech companies. Fueled with plenty of customization options and reskinning ones this eMail client offers a lot for its free price tag. It is also fueled by Mozilla community focusing on privacy and security. It can work with any mail service and it is lightweight with a clean look, altho the look itself can be heavily customized. The bad side is that client itself relies on email services to provide cloud-based emails, so if you are receiving your email via a service that does not have a cloud-based service in itself all of your received emails will be locked to the computer where you have received them. Also customizing it can be sometimes a little too technical for the average computer user. All in all, Thunderbird is one great eMail client and it would be a shame not to use it because of its technical side, if you need a reliable and secure eMail client on a single machine, look no further than Thunderbird.

Paid eMail clients

Microsoft Outlook

https://www.microsoft.com/en-us/microsoft-365/ Outlook comes as a part of the Microsoft Office suite and as one of the oldest eMail clients, it is still widely popular and adopted through many users and businesses. It has tight integration with all Microsoft services and full integration with Calendar making it one of the if not the best eMail client out there. Outlook also has a free online service completely free for personal use as well. The downside is that you can not get it as a separate product if you want a business version other than as a part of the Office suite. The final verdict would be that this is perhaps the best eMail client out but the big downside is that there is no desktop version outside the Office suite.

eM Client

https://www.emclient.com/ eM Client offers a wide array of features, including a calendar, contacts, and chat. Support is provided for all the major email services including Gmail, Yahoo, iCloud, and Outlook.com. The latest version also offers PGP encryption, live backup, basic image editing capabilities, and auto-replies for Gmail. Its automatic system makes it very easy to get emails from other services since there is no manual setting, all that is needed is to type in your email and eM Client will do everything else automatically. A one-time purchase is not pricy and it could offer some features that some free clients are missing. Go check it out with a free trial and see if it is for you.

Mailbird

https://www.getmailbird.com This eMail client's main focus is the simplicity of use with visual appeal while tackling multiple eMail accounts. It has many built-in apps along with a customizable interface. Unlike some more Microsoft-centric email clients, Mailbird Business supports a diverse range of integrated apps, including WhatsApp, Google Docs, Google Calendar, Facebook, Twitter, Dropbox, and Slack, all making for a better-streamlined workflow. The downside of this client is the yearly subscription plan. I think people, in general, want to get away from software subscription plans so I will include this as a downside but bear in mind it is downside just in terms of a business plan not in the client itself.

Inky

https://www.inky.com/ Inky is eMail client if you are looking for security. It uses AI along with machine learning in order to block all types of phishing attacks that can get through to other clients. The proprietary machine learning technology can literally read an email to determine if it has phishing content, and then is able to quarantine the email or deliver it with the malicious links disabled. It also takes things a step further and offers an analytics dashboard, which allows an administrator to see patterns of attacks based on dates, or targeted users. The downside is that client itself is so much focused on security that sometimes some nonsecurity features get overlooked and provide a poor experience but if you need a good and greatly secured eMail client Inky is one to check out.

• After that, right-click on each entry under the Display Adapters. Note that the rollback option is only available if the update was recent. So if it isn’t there, just click on the Update Driver option.
• From there, Windows will automatically check for problems and update the Graphics card drivers.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

Option 4 – Try to reset the Monitor

You could also try resetting the monitor or television using its hardware keys and see if it can resolve the problem. You can just refer to your TV or monitor’s guide for more information on how to reset them.

Option 5 – Try some miscellaneous fixes

Apart from the four given options above, you can also check out some miscellaneous fixes to fix the HDMI connectivity issue and here they are:

• You can try to plug out the HDMI cord/cable from both source and destination and then plug it back in after a couple of minutes.
• You can also check if the HDMI cable you are using is still in working condition.
• You can also try to change the source and the destination of the video and see if either one of them is in a non-workable state.
• Try checking if your settings are how they should be as intended in the “Project my screen” option by tapping the Win + P key combination on your keyboard.

Windows Updates are checked for their validity every time they are downloaded from Microsoft servers just like how browsers check websites for a valid certificate. And so if you got an error message saying, “ Some update files aren’t signed correctly, error code 0x800b0109 ” while trying to update your computer, it indicates that the Windows service was unable to verify the validity of the Windows Update. To fix this error, you can try out the options prepared in this post.

Option 1 – Reboot your computer and try again

Save your work and reboot your computer and then try checking for updates again. In some cases, all you need is a restart to fix errors like error code 0x800b0109.

Option 2 – Try to update Windows after an hour or so

There are times when the issue is from Microsoft’s end. It could be that there’s some issue with Microsoft’s server so it would be better if you give it an hour or so before trying to run Windows Update again.

Option 3 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like Error 0x8007001E. To run it, 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 4 – Delete the contents in the Temporary folder

You can also try deleting the contents in the Temporary folder – all the downloaded, pending, or failed Windows 10 updates. You can do that using the simple and easy steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “%temp%” in the field and press Enter to open the Temporary folder.
• After that, select all the folders and files within the Temp folder and delete all of them.

Option 5 – Clear the contents in the Software distribution and Catroot2 folders

• 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 6 – Install the updates in a Clean Boot State

You might want to try putting your computer in a Clean Boot state and then install Windows Updates again without any trouble. 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” 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.)
• After that, try to install the Windows Updates or upgrade again.
