Ok.. An overall summary of the problem I have ran into.. I installed windows ultimate, everything worked great.. I decided to install Office2003 because thats the only version I had.. It installed, but ever since then, no matter what I click on, I get the windows installer pop up.. It takes about a minute or two and then it goes away.. That ranges from clicking on "Computer", "Control Panel" , or "Firefox".. For every program I click on or run, this pops up.. I've installed the MSI cleanup utility but I get a "system administrator policies are in place that have prevented installation" so i can't run that. I've tried uninstalling office from the programs list, and I get this same message. I have UAC turned off and have tried seemingly everything to solve this issue, but no deals.. I've loaded in safe mode and I get " windows installer is not available in safe mode " .. Any help on this topic would be tremendous, as this is unbelievably annoying..
