Same for Mac OS. AIR 29 was updated today due to Apple store rejections of all AIR apps (https://forums.adobe.com/thread/2472510). Please, add changes to installer config.
Also (maybe not related to installer itself), but seems like I could not make overlayed AIR29 over AIR 28 SDK to work. App compilation fails with errors like Error: Unable to locate specified base class 'spark.components.Application' for component class 'Main'. -- Sent from: http://apache-flex-users.2333346.n4.nabble.com/
