Here is the thing. I put together a cheap gaming PC for my son a couple of years ago. I installed retail Windows 7 professional 32bit (student discount). He played Battlefield 3 on it (and some other things) and it performed fine so far. The thing is, the upcoming Battlefield 4 is rumored to require 64bit OS (and more RAM than 32bit supports, I guess). I downloaded a legal 64bit Windows 7 ISO file. Will the COA key I purchased be good for 64bit version installation on the same PC, or do I need to buy a new copy of windows?
Thanks!
Thanks!
