Custom Actions

[image: with few custom actions and small code in script editor]

The Windows Installer provides many built-in actions for performing the installation process. Standard actions are sufficient to execute an installation in most cases. However, there are situations where the developer of an installation package finds it necessary to write a custom action. Custom action is a way to extend functionality of Windows Installer. A developer can write customization code in a dll or script (like the sample below) for their specific requirements and tell Windows Installer to invoke the code at certain points during setup.

Use arrow buttons to change order of custom action execution.

DLL Custom actions - Creating custom action using either with DLL either being installed or binary file.

EXE custom actions - Creating custom action using either executable either being installed or binary file.

JScript custom actions - Create custom action using Jscript file either being installed or as binary file or using inline script.

VB Script custom actions - Create custom action using VBScript file either being installed or as binary file or using inline script.

Executing application on target  system. - Run application on target machine like command prompt etc.
