What error are you getting?
Are you trying to use the component from VB/Excel/script? You don't need to register .NET assemblies to be able to use them normally

  I'm receiving an error message when trying to reference my dll I've just
built and installed on my development workstation. Where can I find the
proper procedures for developing and then conducting a user test of
installation of the dll on the same machine?
Do I have to unregister the com library first and then install or does the
setup installer take care of that for me?

What are you building? Is it a COM object? What errors are you seeing?

I was getting an error Object null reference even though I had a reference
to my dll.  When I used '<Assembly: PrimaryInteropAssembly(1, 0)>' in my
assembly info file my problem went away.
