This document describes the installation process for the Oracle 12c Client software. The University of Wisconsin-Madison doesn't require any particular version installation of the Oracle client, but for best compatibility, it is recommended users install the 12c client. It is NOT recommended users running the Oracle 11g client update to 12c unless they are experiencing technical issues with the 11g client.
Downloading the Oracle 12c Client
Navigate to the Oracle Database downloads page.
Scroll down to the client options and click the download link for your appropriate OS.
Note: 32-bit Windows applications will not work with Oracle's 64-bit ODBC driver. Therefore, users of 64-bit versions of Windows may need to install the 32-bit version of the Oracle Client if they intend to make ODBC connections with 32-bit applications. For instance, if you are running 64-bit Windows 7 but you plan to use a 32-bit copy of MS Access to connect to EPM, you should install the 32-bit version of the Oracle Client. If you intend to use both 64-bit and 32-bit applications to create ODBC connections, you will need to install both clients.
Accept the 'License Agreement' by checking the box in the popup window.
You will be prompted to sign in with an Oracle account, or to create one (free). Once you have signed in, or created your account and then signed in, you will be asked to download the client. Choose to Save the file to an easily accessible location on your computer's hard drive.
The zip archive containing the client installer is large and may take several minutes to download. Once the download is complete, you can continue to the installation process.
Installing the Oracle 12c Client
Locate the zip archive containing the client installer on your computer's hard drive.

Make sure "Use Windows Built-in Account" is selected, then click 'Next >'..
On the 'Specify Installation Location' screen change the default 'Oracle Base' location to C:\app\, and Software Location to C:\app\client\product\12.2.0\client_1. Click 'Next >' to continue with the installation.
