I just got a new HP laptop and it has Windows 7 Home Premium 64 bit. I am a college student and I got Windows 7 Professional free through MSDN Academics. I tried to Upgrade and it said use Anytime Windows Upgrade, I used it and it said that "This upgrade
key you entered is for an edition of Windows that does not work with Windows Anytime Upgrade." Is there anyway I can upgrade to Professional without a fresh install?
