New Hardware, Upgrade Product Key Invalid. Please Help!
Hi.
I upgraded my Mobo, CPU, installed a new SSD and new data drive.
I own an upgrade Windows 7 Premium disk. I had been running Windows 7 Premium 64 on my previous machine.
Now when I do a clean install, it says my product key is not valid.
Is there anything I can do to be able to use this, or will I need to purchase full version of Windows 7? I hope that is not th answer.
Thanks for your help.
