Custom Actions View
As complex as Windows Installer is, it may not provide all the functionality that you require. Microsoft
allows you to add flexibility to your installation that is not directly supported by Windows Installer
through the use of custom actions.
InstallShield supports custom actions that call a DLL function, launch an executable file, or use a
VBScript or JScript. Examples of scenarios where you may want to use custom actions include the
following:
• Validating a serial number that an end user entered during installation run time
• Checking if a product is installed
• Restarting the target machine after the installation
When you add a custom action in the Custom Actions view, you need to schedule it for one of the
available sequences. For example, you may want a particular custom action to be launched during the
installation immediately after the Setup Complete Success dialog is displayed. In this case, you would
add your custom action to the After Setup Complete Success dialog item in the Custom Actions
view. Once you have added an action to a sequence, you can reschedule it if necessary. For more
information, see Changing When Custom Actions Are Launched.
When you select a custom action in the Custom Actions view, you can configure its settings. To learn
more, see the following:
• MSI DLL Custom Action Settings
• DLL Custom Action Settings
• Executable File Custom Action Settings
• VBScript Custom Action Settings
• JScript Custom Action Settings
For comparisons of each type of action, see Using Custom Actions.
