Try

obj = CreateObjectex("VisionCom.VisionComServer", "", "")

Foxpro'll attempt to use default interface for this COM object on the local computer. Remember that the COM object has to be registered on that computer.

I'm thinking that I'm missing something additional that I need to do to allow VPF to create an instance.
