Specify whether an uninstall program is created for the user. The uninstall program is placed in the default directory and creates a hidden file, Unstall.aic, that captures the changes made during the installation. Successive installations modify the Unstall.aic file so that the uninstall program returns the system to its state before the first installation. You can delete any program groups that were created during the installation. Use the Remove Groups During Uninstall option carefully as some users might select an existing group for the installation or add files to the group after installation.
