I actually figure it out. You need to use the Bootstrapper.Command.Action method that returns a launchaction. So you will need to compare it to LaunchAction.Install. So the code will look like.... Bootstrapper.Command.Action == LaunchAction.Install
I hope this help other in the future. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/How-to-retrieve-a-install-uninstall-event-data-within-a-bootstrapper-application-tp7596338p7596349.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users
