The most common reason for needing the 32-bit client is an architecture mismatch between your application and your operating system. For example, you might be running a 64-bit version of Windows, but you plan to use a 32-bit application—like an older copy of Microsoft Access—to create ODBC connections to an Oracle database. In this case, the 32-bit application will be unable to interact with the 64-bit Oracle ODBC driver and will fail. A 32-bit client must be installed to bridge this gap.
