Ive had the exact same problem as you when having I.E run with my first
account, the latter account with fast user switching would result in explorer
having a runtime error message.
Other posts have quoted uninstalling the toolbars and what not, but have not
been helpful.
Microsoft has acknowledged this as problem:
http://support.microsoft.com/kb/884538/en-us
However the hotfix that they supposedly have available is not available for
download?
If anyone has that fix, can they email it?
Furthermore, upon my research I did read something about registry entries,
from uninstalled programs that linger around being called by reference, but
having no physical location to run their program, resulting in the error
message.
So im gonna go ahead and try Registry Pro as one of the guys here have
recommeneded.
The funny thing is it all just started happening very recently. After my ms.
security updates
But im sure the two cases are not at all related
.
Overall though, I have yet to fix this problem.
Any thoughts, inputs would all be appreciated.
