So you are trying to uninstall the trial version of Office, not XP?
If yes, go to the control panel-->add/remove programs-->you can uninstall office trial version there.
I have tried that and about three quarters of the way through the process I get an error message. error 1316 and am told to go toC:\program files\microsoft office\office 10\1033\set up help. When I do this I get "improper file path check for spelling and try again. This continues to repeat.
I have noticed that the pop up message I get asking me to insert the windows office XP professional disc only occurs when I attempt to access an internet site. Local program on my computer do not prompt the message?
