Is it possible to create a new COM Driver interface specifically IDispatch interface?

I have a particular application which requires me to use the COM Driver interface. But the interface does not exist in the library folder which I got with the application. I have no clue where to start from. I can see the Interop Assemblies (e.g CHR.CHRLCD.Interop dll) and I added them as reference in the project but then it is asking me to add some Libraries. Can anyone explain where do I start from?
Thank you
