The Publishing advanced setting allows you to specify publishing information for your component. Publishing is a type of advertising (“just-in-time” installation) in which no user-interface elements are created for the component during installation, but the component can be installed through the Add/Remove Programs applet of the Control Panel or when an installed component requests the published component from the installer.

You must create at least one GUID for each advertised component, known as the componentID, and at least one qualifier under the componentID. (Do not confuse the componentID with the GUID you created in your component's property sheet; they must be unique values.) To add a componentID, right-click on the Publishing item and select New ComponentID. InstallShield generates a new GUID. Press Enter to accept the new GUID.

Each componentID must have at least one qualifier. The qualifier is a string that you can use to distinguish this language or version of the component from any other (for example, to specify a language). It must be unique for the component. To add a new qualifier, right-click on the componentID and select New Qualifier. InstallShield creates a new qualifier with the default name New Qualifier-n (where n is a successive number). Enter your own qualifier to replace the default name.
