  5. Place the downloaded d3d12.dll into the System32 directory.

  6. Register the DLL:

  7. Open Command Prompt as administrator.

  8. Execute: regsvr32 d3d12.dll

Using System File Checker (SFC) and DISM

  1. Run System File Checker:

  2. Open Command Prompt with administrative rights.

  3. Execute:
    sfc /scannow

  4. Wait for the process to complete and fix any corrupt system files.

  5. Use Deployment Image Servicing and Management (DISM):

  6. Still in the Command Prompt, execute:
    DISM /Online /Cleanup-Image /RestoreHealth

  7. This repairs system images and handles deeper corruption issues.

  8. Reboot the PC and check if the d3d12.dll error persists.
