How to Fix 0xc000007b Application Error (Windows 7 64bit)


Method 5: Reinstall (replace) D3DX9_43.dll library

Sometimes 0xc000007b error error can also be related to corrupted or outdated version of D3DX9_43.dll library, used by many graphically advanced video games.

This is especially common with Grand Theft Auto V.

To replace this library and fix the problem, please run through the following steps…



1  Download D3DX9_43.dll library file.

2  Extract downloaded file using WinRar archiver or 7-Zip and you’ll get two versions of D3DX9_43.dll library, each located in corresponding folder.

3  Copy one library to C:\Windows\SysWOW64 , and the other one to C:\Windows\System32. If Copy File dialog prompts, choose Copy and Replace.

Note: although these libraries aren’t essential part of OS, you might want to backup your original files and restore it later, if this method doesn’t help you solving 0xc000007b error.
