I made the mistake of cleaning up unused apps from my PC. In the process, IE6 stopped working (C++ abnormal termination error) UNLESS the Third Party Extensions tab is unchecked in Internet Options. I reinstalled IE6, but that did not fix the problem, and now I can't use valued extensions like Roboform. Is there an easy fix to this problem? Is there a way to determine what Third Party Extensions are actually still on my machine, and some way to remove offending ones and thereby possibly re-enable the ones I really still want by successfully turning this option back on?
