Initialization Handlers

InstallShield 2016 » InstallScript Language Reference

The following event handlers are called directly by the installation engine in InstallScript projects:

Initialization Handlers
Event Handler	Project Type	Description
OnCheckMediaPassword	InstallScript	Called directly by the framework during initiation to query the end user for the installation media's password if the password is not already in the installation log file (as it is if the installation is running as a maintenance installation or uninstallation) and you selected the "Show Password dialog box during setup initialization" check box in the Release Wizard's Password panel or set the Show Password Dialog property to Yes in the Releases view.
OnFilterComponents	InstallScript, InstallScript MSI	Called directly by the framework to filter out components in each feature by language and platform. Override this event to perform custom filtering.
OnIISCheckRequirements	InstallScript	This event handler is obsolete.
OnSetTARGETDIR	InstallScript	Called directly by the framework during initialization to initialize TARGETDIR to its default value.
OnSetUpdateMode	InstallScript	Called directly by the framework during initialization to set the UPDATEMODE system variable appropriately to control which UI events are called by OnShowUI.
