I restored my wife's COMPAC Presario (circa 2006) for the first time last night, but the Microsoft Office Enterprise 2007 Key I printed out, courtesy of Belarc, does not work (invalid). When I did the exact operation in June for my Mother-in-Law on the same model/age laptop/MS office, it worked fine. My OEM discs are in transit with a household goods shipment. Any ideas? I just keep getting sent to the Office 2010 website.
