Understanding the Application Error

When running an application or game on your Windows computer, an error message may appear, as shown:

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

In addition to 0xc000007b, this application error is often accompanied by another error code, such as 0xc0000022, 0xc0000142, and 0xc00004ac.

This is a common issue, indicating that a problem is preventing the application from launching successfully. For example, the program is missing key files to run, has compatibility issues, or has become corrupted.

Causes of App Not Starting Correctly

• Corrupted or missing files: Essential files for the app may be damaged or missing, for example, components from the Microsoft Visual C++ Redistributable packages or DLLs (dynamic-link libraries).
• Incorrect permissions: The app may lack the necessary permissions to run, triggering 0xc0000142, 0xc0000022, 0xc000007b, or another code.
• Antivirus interference: Your security software may mistakenly prevent the app from running properly.
• Software conflicts: Other programs may interfere with the target application, leading to an application error.
• System issues: Corrupted system files, an outdated operating system, or failed updates can be possible causes.
• Registry errors: Incorrect settings in the Windows registry, like the LoadAppInit_DLLs key, can interfere with apps.
