The ApplicationUpdater object dispatches the downloadComplete event when
the download of the update file is complete. If you cancel the default behavior,
you can call the installUpdate() method to resume
the update process:
appUpdater.installUpdate(file);
Calling this method causes the updater install an update version
of the AIR file. The method includes one parameter, file,
which is a File object referencing the AIR file to use as the update.
The ApplicationUpdater object can dispatch the beforeInstall event
as a result of calling the installUpdate() method:
UpdateEvent.BEFORE_INSTALL—Dispatched
just before installing the update. Sometimes, it is useful to prevent
the installation of the update at this time, so that the user can
complete current work before the update proceeds. Calling the preventDefault() method
of the Event object postpones the installation until the next restart
and no additional update process can be started. (These include
updates that would result by calling the checkNow() method
or because of the periodical check.)
