My computer is an Asus, 1 1/2 years old, and meets the requirements to run a 64-bit windows 7. I currently have a 32bit vista and I purchased the official windows 7 64-bit disc. I want a custom installation of windows 7 because I read that a 32-bit Vista can't upgrade to the 64-bit windows 7; it can only custom install. I have downloaded the files required: setup1.box, setup2.box, and expandedsetup. Inside the expanded setup folder, i clicked on setup to try to get the installation process started; however, i got the error box saying "the version of this file is not compatible with the version of windows you're running check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher." Since this didn't work, I tried starting up the computer with the windows 7 disc inside, but the computer starts up normally as if the disc isn't there. When I try opening the disc drive through "Computer", an error message pops up saying "this installation disc isn't compatible with your version of windows....." Please help me!!!!
