I posted another thread earlier, but I have narrowed down my problem.

Calling GetInterfaceFromGlobal is returning E_UNEXPECTED when using
Side-by-Side assemblies. I have two COM dlls I'm trying to distribute
reg-free. The first dll utilizes the second. When the second DLL
attempts
to access the GIT to fire an event to the first dll, I am receiveing
E_UNEXPECTED.

I found a small blurb in another forum that E_UNEXPECTED can be returned
if
there is no proxy/stub registered for the interface. The interesting
thing
is that if I access the second dll directlly everything works normally,
the
problem seems to be in the interaction of one side-by-side assembly with
another side-by-side assembly.
