But if you have a windows 7 upgrade disc it shouldn't be a problem. The problems you heard about were those who downloaded the $30 student upgrade and tried going from 32 to 64 bit.
I have two PCs one with 64 bit vista and one with 32 bit vista, I chose the 32 bit for windows 7 because that's my main media center PC. I want to install windows 7 premium 64 bit on my HP media center PC with 32 bit vista premium, it came with a factory image and i already made my Recovery disc. I'm going to have to do a clean install since its 32 bit going to 64 bit. Some people are reporting problems who are in my situation if i was to encounter problems can i just use my recovery disc and go back to vista? If i did encounter problems i want to just go back to vista and install windows 7 on my 64 bit PC. thanks in advance for help.
