Issue: How to fix error code 0xc000007b on Windows 10?

Hello. Could you please help me to fix the 0XC000007B error? The message keeps popping up when I try to run a game or application. It often shows a full message ” Application unable to start correctly” or just the error code. I’m using Windows 10. Thanks in advance!

Solved Answer

The Error Code 0xc000007b is a common Windows problem that flared up with the release of the Windows 10 Anniversary update,^[1] although such errors typically persist over the years. Usually, it emerges right after the installation of patch or feature updates and prevents people from launching specific apps.

The list of apps affected by 0xc000007b error usually differs; therefore, it may block access to Skype, Messenger, Microsoft Office Package, some video games, or any other application that people were used to using before. The error is typically marked with a notification:

Application Error

The application was unable to start correctly (0xc000007b). Click OK to close the application.

Nonetheless, such an explanation is insufficient for ordinary PC users to address the problem from the right perspective. Clicking OK just closes down the app, preventing users from opening it completely, leaving them without any answers.

Many people managed to fix the 0xc000007b error by re-installing the app that throws this error. That’s a good idea if the problem affects only one or several apps, the removal of which does not cause data loss or other inconveniences.

However, the issue usually affects a whole package of applications. That’s because the error code 0xc000007b often occurs due to the missing or corrupted .NET framework 3.5^[2] or Visual C++ Redistributable Packages.^[3]

Without a doubt, this error code is not the only one that is related to the .NET framework or Visual C++ Redistributable packages. If one of these (or both) components are somewhat damaged, you might also encounter the following errors:

• 0x800F081F
• 0x80240034
• 0x80070660
• VCRUNTIME140.dll is Missing, etc.

Applications, games, and programs cannot be launched due to 0xc000007b error on Windows devices.

Fix 8. Check system files for corruption

Windows has great built-in system file repair capabilities, although they can only be used via Command Prompt. Initially, it might seem like it is difficult to operate as it does not have regular UI features (like buttons or icons) that most users are so accustomed to. Instead, you will have to write a few commands – here's how:

• Type in cmd in Windows search
• Right-click on Command Prompt and pick Run as administrator
• In the new window, type in the following command line and press Enter after:
  

  sfc /scannow

• Now wait till the scan is finished – Windows will report its findings. Reboot the PC after.

If that did not help, you can also initiate DISM checkup to fix Windows image files:

• Open Command Prompt as administrator once again
• Type in the following commands, pressing Enter after each:
  

  dism /online /cleanup-image /scanhealth
  dism /online /cleanup-image /checkhealth
  dism /online /cleanup-image /restorehealth
