The application was unable to start 0xc00007b

As you know, one of the basic apps in the Windows 10 operating system is the calculator and it can even be extended to a scientific calculator which makes it really useful for users. However, there are instances when you might encounter some issues while using this app. One of the issues about the Calculator app that’s been reported recently is that the Calculator app is not working. If you encounter the same problem, then you’ve come to the right place as this post will guide you on what you can do to fix the problem. Based on the reports, users claimed that the issue with the Calculator app occurred right after they’ve installed a feature update, while other users claimed that the Calculator app never really worked on their computers and there are also cases where the app opens but it either freezes or crashes. According to researchers, the main causes of the problem include a feature update that could’ve altered the settings. It could also be due to problems with the login account or corrupted and missing files, or the problem could also with the calculate app itself. To resolve this problem, here are some suggestions you can follow.

Option 1 – Run the System File Checker Scan

System File Checker or 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 to good system files that might be the reason why the calculator app is not working properly. 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.

• Reboot your computer.

Option 2 – Run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” that could help in fixing the Calculator app.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism (.)exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 3 – Try logging into your computer using a different User Account

You might want to try logging into a different User Account since it is possible that the issue could have something to do with your log-in account. Thus, you can isolate this possibility by logging into a different user account. If you don’t have any other user account, simply create a new one by clicking on the Start icon and then go to Settings > Account > Family & other users. From there, go to the Other user's section and click on the Add someone else to this PC option, and then inputs all the needed information and restarts your computer. Once your computer has restarted, log into your computer using the newly created user account.

Option 4 – Try to reset or reinstall the Calculator app

If the first three given options didn’t work, you might want to reset or reinstall the Calculator app. To do that, follow these steps:

• Click on the Start button and go to Settings > Apps > Apps and features.
• Next, look for the Calculator app from the app list and click on it to see its other options.
• After that, select the Advanced options and go to the Reset section and then click on the Reset button to reset the Calculator app.

Note: You also have the option to reinstall the Calculator app. All you have the option to visit Microsoft Store and from there, uninstall the Calculator app.

jZip is a software utility published by Bandoo Media and is classified as a Potentially Unwanted Program. The software is an archive tool that used to compress and extract files in the rar, zip, and other formats. The program is typically bundled upon installation with other unwanted applications and is itself often installed in co-bundles. As of publication time, over 40 AntiViruses have flagged jZip as malicious or potentially unwanted.

It injects itself in Windows shell, providing quick access to the program by right-clicking on any file. jZip displays it's advertising in your browser, instead of the default search results, to better do this, it collects information about your browsing history and your current browsing session, so it can better target ads. This software, upon install, defines an auto-start registry key in your system, this allows the software to launch every time your computer is rebooted, no matter what Windows account you log in to, it also adds Windows Tasks, to allow it to launch by itself at random times, even when closed.

About Potentially Unwanted Applications

If you have ever downloaded software programs from the internet (shareware, freeware, etc,), odds are high you’ve unintentionally installed unwanted programs on your personal computer. Potentially Unwanted Programs (PUP), also referred to as Potentially Unwanted Applications (PUA), are applications that you never wanted in the first place and quite often come bundled with freeware software. Once installed, most of these applications can be hard to remove and become more of a nuisance rather than a necessity. The idea of PUP was actually coined to define this crapware as something other than malware. The primary reason for this is that most PUPs get into users’ computers not because they exploit security vulnerabilities, for instance, but because the users grant consent to install it – unwittingly in many instances. Nevertheless, there isn’t any doubt that PUPs are still bad news for PC users as they could be incredibly damaging to the computer in lots of ways.

What do PUPs do on your computer, precisely?

The unwanted programs after installation display a lot of annoying pop-up advertisements create fake alerts, and quite often it even pushes the end-user to buy the software. PUPs which come as browser add-ons and toolbars are widely identifiable. Not just they needlessly take up space on your computer screen, toolbars could also manipulate search results, monitor your browsing activities, decrease your internet browser’s overall performance, and slow your net connection to a crawl. They might seem innocent but PUPs tend to be spyware. The worst part of setting up a PUP is the spyware, adware, and keystroke loggers that might lurk inside. Even if the PUPs aren’t inherently malicious, these programs still do absolutely nothing good on your PC – they will take valuable system resources, slow down your computer or laptop, weaken your device’s security, and make your PC more susceptible to trojans.

Some tips on protecting yourself from unwanted software

• Read the EULA meticulously. Look for clauses that say that you have to accept advertisements and pop-ups or bundled programs from the company. • Typically, when setting up a program you will get two options, ‘Standard Installation (recommended)’ and ‘Custom Installation’. Don’t pick ‘Standard’ as unwanted programs will automatically be installed that way! • Have a solid anti-virus program such as Safebytes Anti-Malware that will protect your personal machine from PUPs. Once you install this software, the defense against viruses and PUPs is already switched on. • Avoid installing freeware software you will not utilize. Turn off or get rid of toolbars and internet browser extensions you don’t really need. • Only download programs from the original providers’ websites. Avoid download portals since they use their own download manager to bundle extra programs along with the initial download.

Can't Install Safebytes Anti-malware because of a Virus? Do This!

Malware may cause several kinds of damage to computers, networks, and data. Some malware types alter browser settings by including a proxy server or change the computer’s DNS configuration settings. In such cases, you will be unable to visit some or all of the websites, and therefore unable to download or install the required security software to clear out the infection.

After you restart the PC into Safe Mode with Networking, you may download, install, and update the anti-malware program from there. After installation, run the malware scanner to remove most standard infections.

Download the security program using an alternate internet browser

Web-based viruses can be environment-specific, aiming for a particular web browser or attacking particular versions of the browser. The most effective solution to avoid this issue is to opt for an internet browser that is known for its security measures. Firefox contains built-in Phishing and Malware Protection to help keep you safe online.

This error is usually generated because of a conflict arising between Google Chrome and the antivirus program running on the user’s computer. Primarily, error 103 is an incompatibility issue. It is not critical in nature. However, since it will disrupt the smooth functioning of the browser, it is strongly advised to rectify this error that is generated due to any temporary conflicts between the logic of the two programs namely Google Chrome and antivirus. In layman's terms, it would be only justified to say that this error has a lot to do with the way programs react to each other in real-time.

Error Code 0xC004F00F – What is It?

Error Code 0xC004F00F can appear during the Windows 10 installation and activation process. It is a fairly straightforward error code that occurs when a product key is entered in that is unable to be used to complete the final activation of the new operating system. This error code is most commonly related to the installation of new pieces of hardware on a machine that was already running Windows 10 at a previous time.

Error Code 0xC004F00F can also appear on other versions of the Windows software, so if you are not specifically trying to install and activate Windows 10 when this message appears, you may want to contact a qualified Windows technician to help resolve your system error, as the error code has different causes and resolution methods on other versions of the Windows operating system.

Solution

Error Causes

In some cases, Error Code 0xC004F00F will show up if you are attempting to install Windows 10 on a computer in which the hard drive has been replaced or significantly altered. It can also appear when other major pieces of hardware, like the motherboard, have been changed out.  These pieces may be changed as part of an upgrade to new or better hardware or be changed due to the malfunction of the original pieces of equipment. Because it may appear to the Windows activation servers that you are attempting to use the same product code that you have used before to activate what appears to be a new machine (even if the machine is the same one, just with some new parts), you may see Error Code 0xC004F00F arise.

Error Code 0xC004F00F can also come up if you have installed Windows 10 on your machine in the past and have already used the product key that you are attempting to use again.

Further Information and Manual Repair

Error Code 0xC004F00F most commonly appears for users who have made major hardware or software changes done on their machine. Because this error specifically arises from the Windows activation servers believing that your computer is a new one, you’ll need to get in touch with the Windows support team in order to resolve the error. From their database, they will be able to confirm that you are not using a new computer and will be able to bypass the error, allowing you to complete the Windows 10 Activation process.

If you haven’t installed or replaced any of the hardware on the computer, but are still seeing Error Code 0xC004F00F arise during your Windows 10 installation, you will still need to get in touch with the Windows support team to bypass the error code.

Calling the Windows' Support Team

When you call into the Windows support team, you’ll want to specifically have a list of the following information readily available: Which pieces of hardware have been changed out on your computer prior to the installation and activation, what method you were using to install Windows 10, which version of Windows 10 that you were attempting to install, whether it was a single-use or multiple-use license, and basic details about your PC like its make, model, and age.  You may also want to have the product key that you were attempting to use when Error Code 0xC004F00F first appeared.

By having all of this information ready and on hand ahead of time, you’ll have a greater likelihood that your error will be able to be resolved quickly and efficiently, avoiding long periods spent on the phone with customer service. Make sure that you specifically mention that you are experiencing Error Code 0xC004F00F during the Windows 10 activation process when you call into the Windows support team so that you can be connected to a representative who is equipped to help you resolve this specific problem.

Getting a Qualified Technician

If you are not comfortable in working with the Windows support team or have not been able to successfully resolve Error Code 0xC004F00F even after getting in touch with customer support, contact a qualified technician who is familiar with the Windows 10 activation process and can walk you through the things that you will need to communicate to the Windows support team in order to have them bypass or resolve the error code.

If you suddenly encounter Activation Error codes such as 0xC004E016, 0xC004F210, 0xC004F034, and 0xC004F00F on your Windows 10 computer, then they all point to the same issue – Invalid Product Key or Version mismatch. When you see any of the aforementioned error codes above, it indicates that you are either entering a wrong product key or you are using an incorrect ISO when installing it on your computer. In such cases, you may see either of the following error messages:

“You are running Windows 10 Pro, but you have a valid digital license for Windows 10 Home.” Or: “The specified product key is invalid or is unsupported by this version.”

If you got the error code 0xC004F00F then it means that you’ve entered a product key for the Enterprise edition of Windows to activate Windows 10 Pro or Windows 10 Home. It could be that you have a key from your work and you accidentally use it on your Home PC. If you got the error codes 0xC004E016, 0xC004F210, then it means that you have entered a product key that is meant for a different edition or version of Windows. On the other hand, if you got the error code 0xC004F034 instead, then it means that you have entered an invalid product key or a product key for a different Windows version. Whichever error codes you have, refer to the possible solutions given below to fix the Invalid Product Key or Version mismatch Activation Error in Windows 10.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve this Activation error is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

Option 2 – Try purchasing a new license

There is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect to your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

Option 3 – Try activating Windows 10 via mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

It is common knowledge that when you open a file that contains viruses, it will automatically infect the operating system. This is why most antivirus programs like Windows Defender won’t allow the opening of a file or execution of any associated program if they detected that the file or program could potentially harm the computer. In situations like this, you may get an error stating, “Operation did not complete successfully because the file contains a virus”. In addition, it is also possible that this error message can pop up even for known programs. To open the program or file that triggered the error, you will be given a couple of options in this post but make sure that the program or file is really safe to open and does not contain any virus. You can open the file or execute the program by disabling the Windows Defender or any antivirus program temporarily. You could also try to add an exclusion in your antivirus program or repair File Explorer or run the Disk Cleanup tool. For more details, refer to each one of the options provided below.

Option 1 – Try to temporarily disable the Windows Defender program

Although you could encounter this error with any antivirus program, it is more common in Windows Defender. Thus, you can try to disable it for a while when you open the file or execute the program. To do so, follow these steps:

• First, click on the Start button and go to Settings > Update and Security > Windows Security.
• Here, select the “Open Windows Security” option located in the right pane.
• After that, click on the “Virus and threat protection” option.
• Next, click on Manage settings under the Virus and threat protection settings.
• Then turn off the switch for both Real-time protection and Cloud-delivered protection.
• Now restart your computer and try to open the file or execute the program again and see if it works.
• Note: Do not forget to enable the Real-time protection and Cloud-delivered protection back in Windows Defender.

Option 2 – Try adding an exclusion in the Windows Defender program

• Open the Windows Defender Security Center from the system tray area.
• Next, click the “Virus & threat protection” option and then open the “Virus and threat protection settings”.
• After that, scroll down until you find the “Exclusions” and click on the “Add or remove exclusions” option.
• Then click the plus button and select the type of exclusion you want to add and from the drop-down list, select Folder.
• Next, navigate to the path where the file or program is located.
• When a User Account Control or UAC prompt, just click on Yes to proceed.
• Now try to run the program or file again and see if it worked. If it did, then make sure to turn on your antivirus. However, if it didn’t work, proceed to the next given options below.

Option 3 – Try to run a System File Checker scan

System File Checker or 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 that might be the cause why you’re getting the errors 0x8024a11a and 0x8024a112. To run the SFC command, follow the steps given below.

• Type “cmd” in the Start search and then right-click on the appropriate search result.
• Next, select “Run as administrator” to open Command Prompt with admin privileges.
• 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.

 Now restart your computer and see if the problem is fixed or not.

Option 4 – Run the Disk Cleanup tool

You can also try using the Disk Cleanup tool. To use it, refer to these steps:

• Tap the Win + R keys to open the Run dialog box and then type “cleanmgr” in the field and hit Enter to open the Disk Cleanup window.
• After that, select the drive you want to clean.
• Now click OK to clean the disk and restart your computer.
