Hello, I have just installed Office 2003 Pro on a Vista Home laptop. When I try to apply the SP3 Service Pack for office it gives me the error "'The expected version of the product was not found on your system". I checked before installing that this install was ok on Vista. I have run the office repair on my install. The disk is good. What am I missing here? This is my first experience with Office 2003 on Vista. I have removed the old office 2007 that had expired along with the 2007 convertor. I can install the convertor later. Is it possible that there are some registry entries from 2007 that are still there and fooling the installer for 2003? Thanks.
