If you are installing the product on a computer with a 64-bit operating system, then you can choose to install the product as either a 64-bit or 32-bit application.

During the product installation, you select either 64-bit or 32-bit mode for the product on the Location page in IBM® Installation Manager. (The Location page is where you select the installation directory.)

  • Some product features might not be available.
