This is really helpful to me. Thank you!
But for my instance, I have to add another two custom actions to stop then start the apppool, so that the site method Application_Setup can be executed immediately.
Besides, somehow NOT (REMOVE="ALL") not work for me, it will execute both in install and uninstall process. So I use this NOT Installed AND NOT REMOVE.

@seansong327 can u share the two custom actions that u have used for stating and stoping the apppool
