What other Windows CD/DVD do you have to qualify?
I purchased Windows 7 Home Premium Upgrade disc couple month ago and had successfully custom install Windows 7 32bit over my Windows Vista 32 bit. My ram was not enough (2 GB) and now I have added another 4 GB on it and trying to find a way to "clean install" 64bit Windows 7 over my 32bit Windows 7 with only the upgrade Disc. What should I do? Thank you so much.
