Supporting Previous Sun Studio Releases

If you installed any previous release of Sun Studio software (Sun Studio 12 software or an earlier release) on your system, then you must uninstall it, or install the Sun Studio 12 Update 1 software in a different directory.

If you used the English-only installer to install some components of the English-only release of the Sun Studio 12 Update 1 software, you can use the multi-language installer to install additional components for the English locale. However, before using the multi-language installer to install Sun Studio 12 Update 1 software for additional locales, uninstall all English-only Sun Studio 12 Update 1 software installed with the English-only installer.

If you installed Sun Studio 10 software, Sun Studio 11 software, or Sun Studio 12 software on a Solaris 10 system, you can install the Sun Studio 12 Update 1 software on that system only if you run the installer from the correct zone.

• On a Solaris 10 system that has Sun Studio 10 software installed, you must run the installer in the global zone, which will install the Sun Studio 12 Update 1 software in all zones.

• On a Solaris 10 system that has Sun Studio 11 software or Sun Studio 12 software installed, you can run the installer in either the global zone or a local zone, but the installer will install the Sun Studio 12 Update 1 only in the zone where you are running the installer.

• On a Solaris 10 system that has no previous releases of Sun Studio software installed, you can run the installer in the global zone to install the Sun Studio 12 Update 1 software in all zones, or in a local zone to install the software in that zone only.
