Solution: Just launch the standalone Flash-Player once manually like “C:\Programme\Adobe\Adobe Flash Builder 4\player\win\FlashPlayer.exe”. The OS (Windows only) will remember the version which you launched at last time. That’s it!

The download links are still available for your OS:

Windows:

http://download.macromedia.com/pub/flex/flex_builder/FB3_win.exe

Mac OSX:

http://download.macromedia.com/pub/flex/flex_builder/FB3_mac.dmg

TweenMax.to(mySymbol, 0, {tint:null});
TweenLite.to(mySymbol, 0, {tint:null});

The Adobe Air 1.5 UpdateFramework still not work with Air2 Native Applications, but you can use it to compare the App-Version and offer download the new installer.exe. We have to stop the Updater to hide the default update Dialog, because it wants to download the *.air file (not usable for us). We need only compare the version itself that we got by setting the “isNewerVersionFunction”-property, and within stoping the UpdateProcess and offer downloading the new Installer.exe:

private function checkForUpdate():void
{
	      // Server-side XML file describing update
	      appUpdater.updateURL = ApplicationController.UPDATE_URL;
	      // We won't ask permission to check for an update
	      appUpdater.isCheckForUpdateVisible = false;
	      //versions detection
	      appUpdater.isNewerVersionFunction = compareVersion;
	       // Once initialized, run onUpdate
	      appUpdater.addEventListener(UpdateEvent.INITIALIZED, updateInitializedHandler);
	      // If something goes wrong, run onError
	      appUpdater.addEventListener(ErrorEvent.ERROR, updateErrorHandler);
	      // Initialize the update framework
	       appUpdater.initialize();
}
private function compareVersion(currentVersion:String, updateVersion:String):Boolean
{
           //stop showing default updater dialogbox
	   appUpdater.cancelUpdate();
	  //compare versions
	if(currentVersion != updateVersion)
	{
		// set an information text for the user
		var dialogCopy:String = "An new version " +updateVersion + " is available. Click to download.";

                 // or directly
		 navigateToURL(new URLRequest("http://urltomyinstallerfile.exe"));
	}

	return false;
}

First: Don’t embed fonts directly into .swc Files. This makes Flexbuilder very very slow!
