I recently modified my development machine by installing networking under WFW. When I finished the process, I found that SETUP.EXE won't run. It detects a "conflict" even tho there are no other apps running. I cannot run the setup's I was developing a few days ago, nor can I run SETUP from a 3rd party disk which I happen to know uses MsSetup.
What is SETUP mis-detecting, and how can I get back to development?
added: The message is the standard "Setup has detected a conflict with a running application. Quit all applications and try again." (or words very close to that.)
