The DLL is a .NET component not a COM component so you can't just CreateObject() on it.

You either need to:

* Register the Component for COM Interop by running RegAsm on it (from Visual Studio SDK)
* Use wwDotnetBridge to use the .NET component directly

I would use the latter route since it avoids having to register anything.

wwDotnetBridge is open source (or comes as part of West Wind Client Tools with some additional features) and source code is on GitHub:
