I downloaded Office XP Service Pack 2 and have tried to install it and it won't take. First it asked me to put in the Office CD w/ Outlook on it which I did. Then it started "Gathering information about Word" and said "The expected version of the product was not found on your system." I have a genuine, non-pirated copy of Office XP Developer, which has been registered w/ Microsoft over the phone. Any ideas/suggestions?
