I resolved this problem by copying stdole.dll to the bad
machines. It would have been nice if Excel told me it
couldn't load the stdole.dll assembly.

I've built an addin for Excel 2002 using managed code.
On
most machines where I've installed the addin, all the
appropriate methods in my implementation of
IDTExtensibility2 appear to be called
good machine addin trace-
OnConnection called
OnAddInsUpdate called
OnStartupComplete called
OnBeginShutdown called

On other machines the OnStartupComplete method is not
called.
bad machine addin trace-
OnConnection called
OnAddInsUpdate called
OnBeginShutdown called

What is causing this inconsistent behavior? How do I
insure OnStartupComplete will always be called? Both
good
and bad machines are running Win2K.
