This could be version related...but this is telling you pretty much what is going on.  When we call the VFP references, we use the OLEDB provider.  So it is going to be pulling this from the registry and relies on it being installed on the machine.  I am guessing that you are running VFP9 on your machine (which is fine) but I have seen issues when more than one version of VFP is loaded on the same machine.  It just becomes a bit of "tinkering" with the VFP OLEDB and VFP runtime files within the SYSTEM32 (or whereever) folder to make sure things are registered properly.
