Unregistered DLL

I am making a program that interacts with WindowsNT Indexing service. I included a DLL into the project, it seems to work fine at design time, but when I goto runtime it gives me an "Unregistered DLL" error.
The DLL wasnt originially on the computer, I had to copy it to the system32 dir from the Win Installation CD.

Anyone know how to Register the DLL?

Thanks,
Steve

sure:

regsvr32.exe (full path & filename)
append a "-u" at the end to unregister

Real programmers don't comment. If it was difficult to write, it should be difficult to read.
