Downloading Oracle Database 11g Release 2 for 32-bit Windows

Oracle 11g Release 2 is not compatible with Windows 10. Windows 10 users should download the Oracle 12.1 client instead. Scroll down to 'Oracle Database Client (12.1.0.2.0) for Microsoft Windows (32-bit)' and click winnt_12102_client32.zip to download the 32-bit Oracle 12.1 client.

At Indiana University, to download the Oracle Database 11g Release 2 client for 32-bit Windows, use either of the following methods:

Download directly from Oracle's website: This method requires a valid OTN (Oracle Technology Network) username and password. If you do not have a valid OTN username and password, visit Oracle Database Software Downloads. At the top, click Sign In/Register, and then follow the on-screen instructions.
Download from IUware: This method requires a valid IU username and passphrase.

For either download method, you must be logged into your computer as an administrator. (Normally, you should refrain from running your Windows computer as an administrator; see About the principle of least privilege)
