3. Copy the DLL file into the appropriate folder.
4. To ensure system stability, run System File Checker (SFC):
bash
sfc /scannow
This command scans and repairs missing or corrupted system files.
Using SFC and DISM tools
- System File Checker (SFC):
- Open Command Prompt as Administrator.
- Type
sfc /scannowand press Enter. -
Wait for the process to complete and follow any prompts to fix issues.
-
Deployment Image Servicing and Management (DISM):
- Open Command Prompt as Administrator.
- Run:
