Had Vista Home Premium. Bought and installed Windows 7 Pro. All programs were deleted when I upgraded to Windows 7 Pro., and now I cannot install Office Small Business. Load disc, entered Product Key, but get message saying: Set up can't find a version of Microsoft Office on your computer. Hit Browse/Computer/c:/Windows.old/Program Files/Microsoft Office/ok/continue. Get message: The path you have chosen does not point at a qualifying upgradable product. Don't want to upgrade. Just want to install my purchased copy of Microsoft Offe.
