You might have faced The application was unable to start correctly (0xc000007b) error while running an application or a game . This error usually occurs in programs that uses DirectX, that’s why this error is popular among games like GTA 5, Call of Duty, Max Payne 3, Far Cry, Assassins Creed,  Battlefield.

There are several reasons why this error can occur, here are some of the reasons:

  • A program of 32-bit tries to run in a 64-bit system.
  • Due to damaged application files or system files.
  • The installation of updates might be interrupted.
  • Deletion of software directly from the installation folder.

  • First you need to download some DLL files  – Download
  • Once it’s downloaded, extract it and copy the DLL files.
  • Now go to your C drive and navigate to C:\Windows\System32.
  • Here paste the copied files, if you get a prompt to replace the files then replace them.
