Project: This information applies to InstallScript MSI projects.

The OnAdminInstallUIBefore event handler responds to the Admin Install UI Before event. It performs tasks that must take place before data transfer for an administrative installation of an application. To perform an administrative installation, the user launches Setup.exe with the /a switch.

Typically, this handler calls the SdWelcome and AdminAskPath functions to welcome the administrative user and prompt for a destination directory.
