How to enable auto update by Installation parameter

Question

i'm trying to install flashplayer11-2_p5_install_win_ax32_013112.exe by command line FP*.exe /install.
after the installation completed, i check the Update option in control panel.
The "Notify me when updates are available" option is aways selected. It seems that is the default settings.
now, I'd like to know is there any parameter can enable this option "Install Update automatically when possible" druing silent installing.

Hi All,,
Got solution. call checkUpdate() function in application level initialize event.
private function checkUpdate() : void
                appUpdater.updateURL = "http://www.aa.com/flex/aa/NativeUpdater.xml";
                appUpdater.addEventListener(UpdateEvent.INITIALIZED, updater_initializedHandler);
                //we can hide the dialog asking for permission for checking for a new update;
                //if you want to see it just leave the default value (or set true).
                appUpdater.isCheckForUpdateVisible = false;               
                //we initialize the updater
                appUpdater.initialize();   
             * Handler function for updater_initializedHandler events triggered by the ApplicationUpdater.INITIALIZED
             * @param updater_initializedHandler
            protected function updater_initializedHandler(event:UpdateEvent):void
                //initializeHandler();
                appUpdater.checkNow();
In NativeUpdater.xml
<?xml version="1.0" encoding="utf-8" ?>
<update xmlns="http://ns.adobe.com/air/framework/update/description/1.0">
     <version>2.0</version>
      <url>http://www.aa.com/flex/aa/AutoUpdate.air</url>

Upload NativeUpdater.xml file on your Server. When you open your old .air file it will ask for replace with new version.
