An Interop DLL is a .NET assembly that sits between your application and a COM component, allowing them to INTEROPerate with each other. If only your application and the Interop library are present then the system will fail. Your users still need to have the appropriate COM component registered on their system. What COM component is it and how did you get it on your system? Can I assume that its Windows Live Messenger? If so then presumably your users must install Windows Live Messenger.

You don't register an Interop library. The Interop library sits in the same folder as the application. It's the COM component that needs to be registered, which should already be done if Windows Live Messenger is installed. Beyond that, we can't really tell you anything because the fact that a call to a COM component failed is simply not enough to go on.
