Error 0xC004F074 means Windows or Office cannot reach Microsoft’s activation server. This is almost always a network issue — not a problem with your key.

Restart licensing service
Open Command Prompt as Administrator and run:net stop sppsvc then net start sppsvc
Retry activation.
Activate by phone
