This error code 0xC004C003 recently came into limelight when tons of Windows got deactivated. The message would say "Activation server determined the specified product key has been blocked" or "Error: you are running Windows 10 Pro, but you have a valid digital license for Windows 10 Home"



So if it is not something from Microsoft, then it's a MAK key which has been blocked. These keys are set to activate only set number of computers, and cannot be reused, and hence only installed on computers which do not go through the installation process.

The only solution is to Contact the Microsoft Activation Call Center to obtain a new MAK and install/activate the system.
