All required network software that is supplied by your database system vendors must be 32-bit compliant.
If your application was built with 32-bit system libraries, you must use 32-bit drivers. If your application was built with 64-bit system libraries, you must use 64-bit drivers (see "64-Bit Driver Requirements"). The database to which you are connecting can be either 32-bit or 64-bit enabled.
