existence7 0 Posted March 17, 2006 Help! For some reason when I go to the Microsoft website to up date my Office software I end up getting the error "software not installed"... I followed MS bulletin advice to check originating source keys, changed it in the registry, tried the full install for service pack 2 for Office 2003 and still it won't update. I have a legitimate version of this software and was able to update it last in Dec 2005. Now for some reason it is blocked. Will uninstalling the software and reinstalling the software fix this? thanks in advance! Robert Share this post Link to post
