Can anyone help? My dad bought a new computer earlier this year. It came pre-installed with Works 7.0. He requested a copy of Excel for Father's Day, so I ordered and sent him a stand alone copy of Excel 2003. He installed Excel yesterday. It installs fine, but when he opens Excel it asks for the product key. He enters the product key and it tells him that the key is invalid. I did some research and found KB article 836178 which talks about the same problem, only with Office 2003 after another installation of Office 2003. My first question is: Does anyone know if this KB article applies to more than just that situation? (FYI: I really don't understand this fix. In all my years of playing with Office, I was always told to install oldest to newest and the KB article seems to disagree with that.) Next question: Has anyone else run up against the same error on a system with Excel 2003 and Works 7.0? If so, how did you fix it? Finally, the KB article says the solution is to un-install the previously installed version and re-install the new version of Office. His machine is an OEM machine and it appears that he doesn't have the CDs to re-install Works. If I get him Works from the Company Store and send it, will he be able to get around the problem by un-installing his version, installing Excel and then installing the new copy of Works?
