Fix: 0xc00007b Error “Application was unable to start correctly”

The most common cause of the 0xc00007b error is missing or corrupted Dynamic Link Library (DLL) files, which are necessary for the application to function correctly. Since DLL files are loaded into RAM to produce graphics, music, and other features, corrupted DLL files might be caused by malware or third-party antivirus software. Therefore, the antivirus program may corrupt the DLL files in order to lower memory use when they use a lot of RAM.

DLL Files: 0xc00007b Error

Additionally, if you obtained the software or game from a third party or if you are using 64-bit Windows with 32-bit DLL files, this issue might also happen.

A single application or several at once can use DLL files. They were created to lessen the quantity of code required by a program to generate essential functions like generating visuals and music. DLL files are included with Windows components; however, you can get them automatically by downloading the VC runtime if they get corrupted.

1. Set up the module for DirectX.

You can attempt to reinstall all versions of Microsoft Visual C++ as they contain several DLL files that are utilized by apps for different purposes, and as corrupted DLL files are the main cause of this error, you can do that. Installing every component that contains a DLL file or downloading a single DLL file and replacing it with the corrupted one are the two methods available for restoring corrupted DLL files.

Please take the following actions to reinstall the Microsoft Visual Redistributable:
