Hi Tracy,

as the Dll seems to be a kind of mediator, how about talking to that mediator not from vfp but from other directions ?
First of all I'd try accessing the mediator from another dotnet app to talk to the 3rd party
to make sure instatiation does succeed there - should work with and without COM registration.
If that works, COM barfs - then I'd quick check vfp object browser
but head rather straight for VB6 for fürther tests. FileMon/Procmon on your USB ?
Just log in case of security raising one hydra head...

regards

thomas
