Register the DLL with RegSvr32. Quit Excel, then go to the Windows
Start menu. Choose Run and enter:

RegSvr32 "C:\YourPath\YourDLL.dll"

Then open Excel and check the references.

I embed an optimization library in Excel models. I installed a new

to point the Reference to the new folder location, it keeps pointing
back to the original. I even renamed the original folder to see if
causing it to be "missing" would force the redirect. That does not
work.

See what I mean?

How do I kill an obsolete Reference. Can I declare the Reference in
the code inself? Any ideas?

Thanks,
