And?

Are you running a 64Bit app and referencing 32Bit Oracle drivers?
or
32Bit app trying to reference 64Bit Oracle drivers?

The Bit versions of the applications need to match up.

And?  I'm not seeing the problem.  The error message told you what was wrong:  Bit mismatch.

With 32Bit Visual Studio, you'll need the 32Bit Oracle drivers.
