During the installation process, you must specify a package group for the Rational Functional Tester package. A package group represents a directory in which packages share resources with other packages in the same group. When you install the Rational Functional Tester package using Installation Manager, you can create a new package group or install the packages into an existing package group. (Some packages might not be able to share a package group, in which case the option to use an existing package group will be disabled.)
Note that when you install multiple packages at the same time, all the packages are installed into the same package group.
A package group is assigned a name automatically; however, you choose the installation directory for the package group.
After you create the package group by successfully installing a product package, you cannot change the installation directory. The installation directory contains files and resources specific to the Rational Functional Tester product package installed into that package group. Resources in the product package that can potentially be used by other package groups are placed in the shared resources directory.
