Specify whether InstallShield should stream the contents of each of the custom action help files into the .msi file every time that a release in the selected product configuration is built. The path to a custom action's help file is indicated in the Help File Path setting in the Custom Actions and Sequences view (or the Custom Actions view).

Selecting Yes is helpful if system administrators deploy your product to enterprise environments; they sometimes need to know what the custom actions do. If you select Yes, the following tasks occur at build time:

- InstallShield adds the ISCustomActionReference table to the .msi file that is being built. The contents of all of custom actions' help files that are specified in the Custom Actions and Sequences view (or the Custom Actions view) are streamed into the Description column of this table.
- If your project includes any merge modules that contain custom actions, the contents of the help files that are specified in the Custom Actions view of the merge module projects are also included in the ISCustomActionReference table.

For more information, see "Documenting the Behavior of Custom Actions" in the InstallShield Help Library.
