The scenario you are describing is rather less common as usually the after-install executions need top be elevated (e.g. product itself or its config util) That is why the AfterInstall event handlers are scheduled by Wix# as deferred (elevated).
Meaning that events are not completely suitable for you. You will need to use managed custom actions instead. The code below shows how to start Notepad with normal user privileges:
