CCW / REGASM question - error 80070002

I am trying to call my class library from VBA, have registered the dll with
regasm, and see information with progid in the registry, but when i try to
CreateObject("Assembly.Class") I get error 80070002, "automation error, the
system cannot find the file specified". I am using the progid i see in the
registry.

My library is not in the GAC, I found an article saying that if you put the
dll in the win/system32 dir that the CCW would be able to find your dll?

Thanks in advance!
