I have Windows XP (legit) and Office XP (non-legit) on my Dell Inspiron 6400. Automatic update is trying to install the lastest service pack which it's downloaded, and when it tries to install an error comes up saying it can't find proplus.msi, and cancels. I don't have the CD as it's non-legit and evidently don't have the file. I'm not really bothered by not getting the service pack update, but it tries to install the update every time I boot up, and it's locking up my computer. How do I get rid of the downloaded update to prevent it trying to install? Thanks.
