I'm not sure that is quite right. One of the "upgrade" options is to choose a clean install. IIRC you have to enter the Vista 25 character licence and then the Windows 7 key but I can't find this anywhere at the moment. Start the installation and see what happens, it's only a few minutes to get to the key stage.
