PC had 98SE and Access 2002 on it, I upgraded to 2000 Pro (I am domain admin and had local admin rights to PC), when I tried to open Access it prompted me for the CD and apparently got whatever it needed and worked fine after that. However, when the user logs in (she has local Admin and domain user rights)it again prompts for the CD but then gives a Windows Installer error. Right before I upgraded her PC I successfully upgraded another PC configured the same way and when it asked for the Access CD under that users ID (same rights as the user with the problem) it simply got what it needed from the CD and worked fine. I've tried uninstalling Access under her ID and I get the same Windows Installer error I got when I tried to start the program. I logged in under my ID, uninstalled Access, rebooted, and reinstalled. Once again it worked under my ID but not hers. I anyone has any ideas please let me know. Getting to the point of making a backup of her systema and rebuilding from scratch.
