While running an InstallShield based installer, my Windows 7 machine became unresponsive. After forcing a reboot, I can log in to the system, but explorer does not run.

I can log in as a different user without issue and when I change UAC to its lowest setting, I can log in as the user that was performing the install. However, if I re-enable UAC, I am unable to get explorer to run again on login.

I have checked the HKCU\Software\Microsoft\Windows\CurrentVersion\Run and HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce, but don't see anything that isn't configured to run on startup.

I completed the installation of the software as the "good" user without issue.

This is very strange behavior. You should try to set the user to an "Administrator" if they are not already. What sort of software are you installing? It may be a corrupt user profile in that case follow the Microsoft kb and migrate the user to a new account http://support.microsoft.com/kb/811151

Good Luck

I'd also suggest running SysInternals Autoruns to see if there is anything else loading that is potentially causing this problem, perhaps it was related to the installer you ran: technet.microsoft.com/en-us/sysinternals/bb963902 –  Ruairi Fullam Jul 6 '11 at 0:43
