If your system has all of the prerequisite software required by the components you are installing, the installer reports that no prerequisites are missing. If your system is missing any of the prerequisite software required by the components you are installing, the missing software is listed, and you are given a choice of installing it or not. Type 2 and press Enter to install all of the missing prerequisite software. The installer does not report the absence of the patches required by the JDK software, and does not install them if they are missing.
If you have any release of Sun Studio software installed on the system where you are running the installer, the release name, the installation directory, and the installed components are listed for each release.

If you have previously installed some components of the Sun Studio 12 software, the installer displays that installation directory and will install additional components in the same directory.
