Thanks for answering so quickly.

I resgistered as an administrator, yes.  I haven't tried escaping the
'/'. I should've thought about that!

However, I think I may have fixed the problem myself, with some help
from a collegue. We checked the registry to see if the DLL was indeed
registered. It was registered under the name "Graybox.OPC.DAWrapper", so
I figured I'd try using this in Win32OLE's new function, as so :

test = WIN32OLE.new('Graybox.OPC.DAWrapper')

It seems to work so far since I don't have the error anymore and I've
successfully called one function.
