Presenting a custom application update user interface

AIR includes a default update interface:

This interface is always used the first time a user installs a version of an application on a machine. However, you can define your own interface to use for subsequent instances. If your application defines a custom update interface, specify a customUpdateUI element in the application descriptor file for the currently installed application:


When the application is installed and the user opens an AIR file with an application ID and a publisher ID that match the installed application, the runtime opens the application, rather than the default AIR application installer. For more information, see customUpdateUI.

The application can decide, when it is run (when the NativeApplication.nativeApplication object dispatches an load event), whether to update the application (using the Updater class). If it decides to update, it can present its own installation interface (which differs from its standard running interface) to the user.
