0xC000007B 🪟 Windows

The application was unable to start correctly (0xc000007b)

A program loaded a DLL of the wrong architecture (32-bit vs 64-bit) or a corrupted runtime library.

Seen on: Windows

Meaning

0xC000007B is STATUS_INVALID_IMAGE_FORMAT. Typically a 64-bit app picks up a 32-bit DLL (or vice versa) — often a Visual C++ runtime or DirectX DLL copied into System32 by hand.

Common causes

  • 32/64-bit DLL mismatch
  • Corrupted or manually copied Visual C++ / DirectX DLLs
  • Mixed DLL versions in the app folder
  • Damaged game/app files

⚡ Quick fix

  1. Reinstall both x86 and x64 Visual C++ Redistributables
  2. Repair/verify the app or game files
  3. Remove DLLs you copied into System32/SysWOW64 manually
  4. Run sfc /scannow

Detailed fix by platform

Windows

  1. Use Dependencies (successor of Dependency Walker) to see which DLL has the wrong architecture.

How to diagnose

  1. Architecture — Is the app 32- or 64-bit?
  2. DLLs — Which DLL is loaded from where?
  3. Runtimes — Are both VC++ redistributables installed?
