Installer.AfterRollback Event

Occurs after the installations of all the installers in the Installers property are rolled back.

Namespace:  System.Configuration.Install
Assembly:  System.Configuration.Install (in System.Configuration.Install.dll)

'Declaration
Public Event AfterRollback As InstallEventHandler

The following example demonstrates the AfterRollback event. It overrides the Install method and explicitly throws an ArgumentException so that the Rollback method is called. When the Rollback is completed, the AfterRollback event occurs and a message is displayed.
