# Add-on Application

An add-on application is different from a reinstallation/upgrade in that the xxAPPL.TXT information indicates that it is an add-on to an installed base application. An add-on application adds programs and/or data files that are used in conjunction with the existing programs and data files.

Create a new set of menus to access the add-on.

Installable add-on application media must meet the same requirements as application media.

An add-on application must not affect existing live data files.
