I pre-purchased Win 7, and I honestly do not remember being instructed to purchase the bit-version (64bit vs 32bit).
I just downloaded my pre-purchase only to find it's 32bit only. Now I'm trying to reach Microsoft to get the 64bit version.
I'm an experience PC user, been computing for more than 20 years. And I don't remember Microsoft clearly telling me that my pre-purchase must be 64bit, should I require 64bit, which I do.
Also, performing a clean install from the pre-purchase version looks a little tricky.
I expected an ISO so I could burn an install disk......
