Mixed Assembly Problems

[MC-Advantica]

I have a managed C++ based assembly referencing a bunch of unmanaged DLLs. I
strongly name the the mixed assembly, and place it in the GAC. I write a VB
client and reference the managed assembly:

1) What does the managed assembly look at to decide where to look for the
unmanaged DLL dependencies?

2) Why do I run into difficulties running clients EXEs (e.g., VB) against
the GAC based assembly?

I'm using VS2005 for all.

The standard LoadLibrary rules.

I don't know. What kind of difficulties?

Diffuiculties include messages like the following whenever I run any client
app that references the GAC based assembly:

>>An unhandled exception of type 'System.IO.FileNotFoundException' occurred in >>StrongNameGACDebug.exe

>>Additional information: The specified module could not be found. (Exception from >>HRESULT: 0x8007007E)

It's like it cannot find the GAC based assembly or one of its dependencies.
It's dependencies include unmanaged DLLs located back in the GAC based
assembly's build directory.
