I have had the same setup.exe error also and did as you suggested and I still am not able to load my programs. I am running windows vista do you have any suggestions?
I wish I did as I was the one to find out the fix, but it may be just a fix for my computer. The fix was to allow the installer to install the auto as it always would error out while trying.
Make sure you are running vista in classic mode not the default aero mode. Aero does strange things to autos. You may need to run as administrator
