For products that are installed by IBM® Installation Manager, starting the installation process from the launchpad program causes Installation Manager to be automatically installed if it is not already on your computer. Furthermore, the installation process is already configured with the location of the repository that contains the installation package. If you install Installation Manager separately, you must configure the repository preferences manually. Also, you can start the installation of a number of supporting software items from the launchpad.
To install Rational® Performance Tester as a non-administrator, you cannot use the launchpad program to start the installation process. Instead, you must manually run the userinst program from the Setup disk. Running the userinst program provides the same functions as starting the installation of Rational Performance Tester from the launchpad.
