Windows 7: Got the wrong version installed. Need to install correct version

Got the wrong version installed. Need to install correct version

So I bought what I thought what the full version of Windows 7 Pro online for the student discount for $65. I got it all installed and the activation key wouldn't work.

Long story short I got the upgrade version on accident. So I got that refunded and I'm about to just go buy Home Premium. I need to install it. Do I need to uninstall Pro before I install Home Premium? Or will it just get rid of it for me when I install it?

No need to uninstall. The new installer will clear the disk.

Do you have any retail copy of XP or Vista that can qualify you to use Upgrade version - it doesn't even need to be on the drive?

Just use the workaround given here to activate Pro if no qualifying XP or Vista is present: Clean Install with a Upgrade Windows 7 Version
