primary interop assembly conflict?

[keefah]

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.Applica tion it errors
out with “File or assembly name Microsoft.Offic e.Interop.Outlo ok, 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:

Any info or advice would be greatly appreciated.
