Wanting a better method of interop.

Background:  I am writing an application-extension for an existing program which loads a
plain Windows DLL at runtime.  The DLL is coded in unmanaged C++.  It makes calls to C# code
via COM-registered classes.  In addition I have an unmanaged C++-based COM DLL which is used
to call into C# and call into the main DLL, and this is used by C# as a relay to send calls
back into the application via the main DLL.

All the above is coded with Visual Studio 2003.

When I deploy my application, I use regsvr32 on the COM/C++ DLL, and regasm /codebase on the
C# DLL.  The C# code is not strongly named, but I must use /codebase because the application
directory is different from the DLL directories.

Anyhow, I feel that the whole thing is a fragile mess relative to installation issues, and I
want to change something so things are less fragile and less messy.  Maybe using managed C++
somewhere would help, but I don't know how.  Maybe I can eliminate COM somewhere, but I
don't really know about that.  I really don't have a clue where to start, and I don't want
to take on a huge task of rewriting stuff to make the problem go away, but I do want to take
on a manageable task of changing stuff to make the system less messy.

Advice?
