Buying old software is a gamble;sometimes it can be used as is,sometimes upgraded,sometimes it is just a bit of computing history! Sealed copies of older versions of Norton,various antivirus,OSes, and tax programs appear on ebay and at other venues;they are NOT demo versions,but the product has passed its expiration date.
