How To Fix Error 0xc00007b “Application was unable to start correctly” On Windows

Estimated reading: 3 minutes 269 views

The 0xc00007b error primarily occurs due to corrupted or missing Dynamic Link Library (DLL) files, which the application requires to work properly. Corrupted DLL files can be caused by malware or third-party antivirus software, as DLL files are loaded into RAM to produce graphics, audio, and other functionalities. Consequently, when the DLL files consume a large amount of RAM usage, the antivirus software may corrupt them to reduce memory usage.

Moreover, this error may also occur if you have downloaded the application from a third-party source, or if you have 32-bit DLL files with 64-bit Windows.

Below are various methods, most of which are simple, which you can use to try and fix the 0xc000007b error.

Install the DirectX module.

Since this error primarily occurs due to corrupted DLL files, you can try reinstalling all the versions of Microsoft Visual C++, as they contain dozens of DLL files used by applications for various tasks. There are two ways to restore corrupted DLL files: either install all the components containing DLL files or download the specific DLL file and replace it with the corrupted one.

1. Press the Windows + R keys simultaneously to open the Run Window.

2. Enter appwiz.cpl and click OK to open the Programs and Features Window

3. Right-click Microsoft Visual C++ and select Uninstall.

1. Hold down Windows+R keys to open Run.

2. In the Run dialog box, type in CMD and hold down Ctrl+Shift+Enter keys to open the elevated Command Prompt.
