Hello. I have an addin that works fine on XP/Outlook 2007, but once we
install it on Vista, it won't load in Outlook 2007. Looking in the Tools --
Trust Center -- Addins, etc., I see the generic message "Not loaded. A
runtime error occurred during the loading of the COM Add-in."

How can I further troubleshoot this error? I see no logs being generated,
nothing in the Event viewer, etc. How can I determine the cause of this
problem?

I also already tried installing CDO, but that didn't help either.

Thanks in advance for any help provided.
