primary interop assembly conflict?

P: n/a
Hi,
I'm writing a C# web app that uses Outlook to send email. I use a reference
to the Microsoft Outlook 11.0 Object Library, but it's giving me problems. I
tracked down some stuff on the Net about the global assembly cache (GAC) and
primary interop assemblies (PIA) and so forth, and did all the
recommendations, in terms of tweeking Office, installing the .NET Office
stuff for framework 1.1, etc. I got it to the point where it compiles ok, but
during run-time, when I try to instantiate an Outlook.Application it errors
out with “File or assembly name Microsoft.Office.Interop.Outlook, or one of
its dependencies, was not found.” What it seems like is going on is that the
PIA can be found during compile time, but not during runtime. Is there a way
or a switch to throw that would let runtime know to look in the GAC? I think
it might be a Registry thing. Here are the LOG entries that display for the
runtime error:
