Which version should you choose? The one that matches the program showing the error, not Windows: a 32-bit game or program needs the 32-bit DLL, even on 64-bit Windows. If in doubt, try the 64-bit version first, then the 32-bit one if the error persists or becomes “0xc000007b”.

Install Microsoft’s DirectX components

Windows 10 and 11 include DirectX 12, but not these legacy libraries. Microsoft’s official “DirectX End-User Runtime” installs them all at once, without changing the DirectX version of Windows.

Microsoft.com: DirectX End-User Runtime

Download and run dxwebsetup.exe from the Microsoft page, then follow the wizard.
Restart your computer and launch the game again.
