Windows Installer Functions

InstallShield 2020 » InstallScript Language Reference

Windows Installer functions, or APIs, are functions exported by the Windows Installer engine. They enable you to query and temporarily manipulate tables of a running installation.

One common use for adding temporary records to a running database is to populate user-interface elements with data not available until run time. For example, you can use Windows Installer APIs to populate a ListBox control in dialog with a list of mapped network drives, user accounts, directory names, or other data that can be discovered only while an installation is running on a particular target system.

For more information about any Windows Installer function, see the Windows Installer Help.
