Well, at first, I downloaded vista and put it on a DVD (the normal way). But obviously, it won't boot at startup, so I tried to open the setup.exe at mycomputer manually, and it actually installed vista for me. But now, when I try to install some softwares, it always gives me error messags like "A FILE IS CORRUPT" or something. WTF!!!! Anyone have a solution? I've been working all day trying to figure this out.
