I believe that the OCI driver(v.8.1.7) is compatible, but you are missing the DLL for the driver to work, or it can't find the DLL. This is a very common (and annoying!) error that can be frustrating to get right. It took me a couple of days to get mine working...This is one of the advantages of the thin drivers
If you want to trouble shoot this problem, you can start here:

but I would stick with the thin drivers anyway.
