Error code 0xC000007B, also known as STATUS_INVALID_IMAGE_FORMAT, typically appears when you try to run a program and Windows cannot load a required DLL file. This often happens because the program expects a 32-bit DLL but gets a 64-bit one (or vice versa), or a dependency is missing or corrupted. It's a common issue after installing/reinstalling software, especially games or applications from older versions.
