不能支梯子的看下面：

My Problem is i want to update my AIR application from a local system path, it can be central download location or a third app which is monitoring the updates, which downloads the new AIR file to the central location. 

I have tried using installFromAIRFile method from the ApplicationUpdaterUI class to update my application, but no success. I suspect I might be using this message incorrectly. I have attached below the code snippet what i have tried. 

public function updateApplication1():void{
                                var airFile:File = File.desktopDirectory.resolvePath("UtilityWizard.air");             
                    _appUpdater = new ApplicationUpdaterUI(); 
                    _appUpdater.updateURL = airFile.url;             
                    _appUpdater.addEventListener(UpdateEvent.INITIALIZED, updateIntializeHandler);            
                                _appUpdater.addEventListener(StatusFileUpdateEvent.FILE_UPDATE_STATUS, fileUpdateStatusHandler);
                                _appUpdater.addEventListener(StatusUpdateErrorEvent.UPDATE_ERROR, updateErrorHandler); 
                                _appUpdater.initialize();
                        }

  
private function updateIntializeHandler(e:UpdateEvent):void {
                   var airFile:File = File.desktopDirectory.resolvePath("UtilityWizard.air");
                    _appUpdater.installFromAIRFile(airFile); 
                } 

 private function fileUpdateStatusHandler(e:StatusFileUpdateEvent):void{        
                Alert.show(e.available.toString());        
                }

                private function updateErrorHandler(e:StatusUpdateErrorEvent):void{ 
                Alert.show(e.text); 
                } 


Please guide me to the correct path, or that is something not possible. 

Thanks in advance
