Ok so here is my problem I bought paralles and I am trying to install windows 7. The copy of windows 7 I have is pro 64bit I got it off of dream spark. The problem is it loads up windows and starts the setup process then says the code is invalid. I don't see how the code is invalid when it is my code and I haven't used it. I called microsoft and they said they can't help me I need to log on to their forums and figure it out. Can anyone help me?
