Click the ellipsis button (...) to browse to the file that describes the behavior of the custom action. The file should be a text-based file such as a .txt, .htm, or .rtf file.

At build time for Basic MSI, InstallScript MSI, and merge module projects, InstallShield streams the contents of this file into the Description column of the ISCustomActionReference table.

If you are working on a project in Direct Edit mode, InstallShield streams the contents of the file that you select into the Description column of the ISCustomActionReference table as soon as you select the help file. In addition, InstallShield makes this setting read-only and displays [Text Data] as the value for this setting.

The intended behavior of each custom action must be documented for the Windows Vista Quality Program. This is especially helpful if system administrators deploy your product to enterprise environments; they sometimes need to know what the custom actions do. If you validate your installation package but you have not specified a value for the Help File Path setting, InstallShield generates validation error ISICE10. For more information, see "ISICE10" in the InstallShield Help Library.

For any built-in InstallShield custom actions, InstallShield makes this setting read-only and displays InstallShield Custom Action as the value.
