Hi Stuart,
This might have been caused by some corrupted system files. Try running these command:
- Press Windows key and type Command Prompt then run it as administrator.
- Type **DISM.exe /Online /Cleanup-image /**Restorehealth and press Enter.
- Once it's done, type sfc **/**scannow and press Enter.
- Restart your computer and try to install it again.
If the issue persists, go to Services > Remote Procedure Call > Automatic. If the service is running, stop it, refresh and start the service accordingly.
Let us know how it goes.
