Activation fails Error code: 0xC004C003


Hi Roy,

I've tried that cmd code but no joy, same error. I even rolled back to 7, checked everything was fine, windows activated, all up dates installed. I then followed the upgrade instructions again, everything goes smoothly and it is simple to achieve, but it won't activate.
-error-0xc004c003

I've done nothing but follow MS prompts and advice and having no joy. It just doesn't doesn't work.
