I have a machine (XP) that I need to remove ArcGIS 9.3.1 (sp1) from.
When I go through the Windows Add/Remove and do a remove it fails with the following message:
"Error 1500. Another installation is in progress. You must complete that installation before continuing this one."
--The error statement is incorrect. I turned the machine on, logged in, and tried to do the uninstall, so there's not another installation going on.
After this happened I tried to do a repair on the install, hoping that would make it possible for me to then do the uninstall. But that just raised the same error as the uninstall.
