Downloading and Installing Oracle 12c Client
This document describes the installation process for the Oracle 12c Client software.
Downloading the Oracle 12c Client
Navigate to the Oracle Database downloads page.
Scroll down to the list of platforms and click the 'See All' link next to your operating system.
Select the 'Accept License Agreement' option along the top of the page.
Click on the download link for the 'Client' for your version of Windows.
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.
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.
Right-click the zip archive and select 'Extract All...'. Windows will decompress the contents of the zip archive into a folder in the same location.
Open the resulting folder called 'Client32' (or 'Client64'.). Double-click on the application labeled 'setup' to launch the installer program.
On the first installer screen choose 'Administrator' as the installation type.
Click 'Next >' on the language selection screen.
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:\Oracle32 if you installed the 32-bit client, or C:\Oracle64 if you installed the 64-bit client. Click 'Next >' to continue with the installation.
The installer program will check for prerequisites and initiate the installation process. Once the installation is complete, you will be taken to a summary screen.
