This is kinda strange, but I've got two Windows 7 licenses, one for Home Premium and one for Professional. I installed the one that was an upgrade that came with my wife's computer on my (slightly older) Vista machine about six or eight months ago. No problem, blew my machine away and did clean install.
Now I've bought the student version so we can have both machines on 7. Problem is, it is the Professional version, so I can't do an upgrade install on her machine because it's moving to a "higher" version, I guess.
I don't want to blow her machine away because it has a ton of games on it (that's about all she uses it for), but want to upgrade in place. So I'm in the weird situation of having the wrong version on the wrong machine.
So, is there any way around this problem? Could I install the upgrade version over my Home Premium version in an "in place" upgrade and then use the disks that came with her upgrade to do an in place upgrade of her Vista machine? What I'm worried about is the serial numbers -- the one has already been registered and activated on my machine, so I don't know what would happen regarding licensing if I tried this.
Any help would be sincerely appreciated! Thank you.
