Flash Builder 4 and Adobe AIR 2

Question

I'm trying to figure out how to use AIR 2 with Flash Builder 4.  I was initially under the impression that FB4 has AIR2... but the when I create a File object and try to call the function openWithDefaultApplication().  An error occurs saying the function doesn't exist.  This is the AIR application I created in FB4.  Am I doing something wrong or do I need to install AIR 2 somehow -- and if so, how do I do so?
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
                            xmlns:s="library://ns.adobe.com/flex/spark"
                            xmlns:mx="library://ns.adobe.com/flex/halo">
     <fx:Script>
          <![CDATA[
               private function launch():void{
                    var myfile = new File("C:\Windows\notepad.exe");
                    myfile.openWithDefaultApplication();
          ]]>
     </fx:Script>
     <s:Button x="439" y="155" label="Button" mouseDown="launch()"/>
</s:WindowedApplication>
Thanks in advance.

Hi Sumeet,
Unfortunately we don't have support for sidecar installs with native installers at this time.  I've seen this come up before but when I searched the ideas.adobe.com site I couldn't find a specific feature request.  We are aware that there is interest in this feature, but I'd like to encourage you to add a post to the ideas.adobe.com page or over at bugbase.adobe.com and let others know so we can vote on it.
Thanks,
Chris
