i purchased windows 7 ultimate upgrade on dvd and ran anytime upgrade to install it. the key was entered at this time. all seemed ok, ultimate worked fine. now i need to activate ultimate but when i enter my ulitmate key i receive a message saying that i can only use this key to upgrade not a clean install. i have not performed a clean install, nor do i want to. the original key for 7 starter is not accepeted either. The window 7 ultimate upgrade disc appears to be genuine from a reputable dealer. i now have a message on my screen saying this windows is not genuine.
how do i fix this ?
