This article describes the procedures for acquiring and installing the Microsoft Oracle ODBC Driver version 2.5, which is a component of the Microsoft Data Access Components (MDAC) version 2.0 and higher.

The Microsoft Oracle ODBC Driver version 2.5 is part of the Microsoft Data Access Components version 2.0 and 2.1. You will need to download this "stack" from the Microsoft Web site and install them.
