window installer runs as Access launched

I have a Windows 98 machine and have Office Professional XP installed and everytime Access, and only Access, is launched, the windows installer comes up and runs. The application works fine,this is more of an pain than anything. Have checked versionof Windows installer and it is version 2 and Office is SP2. Word, Excel etc. launch fine, no issues there, only Access. Have also tried reinstalling it. Any help would be appreciated.
