Hello
you cannot use the pro key directly on a home edition.
Use the generic key to install Pro first, then use your own key to activate it after that.
You can go to Settings > System > Activation > Change product key
Disconnect internet, and disable any third party antivirus, key in the generic key instead: VK7JG-NPHTM-C97JM-9MPGT-3V66T
That should get you to Pro. Once restarted, you can connect back to the internet, then this time key in your own product key
