Problems loading Flex3 swf into AIR app

Question

This is a challenging problem that I have reduced down to the
bare minimum and it is still reproduceable. I have built a minimal
AIR application and added a SWFLoader to it which loads a SWF file
named "Junk.swf" using an absolute path.
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute" title="Hello World">
<mx:Style>
WindowedApplication {
background-color:"0x999999";
background-alpha:"0.5";
</mx:Style>
<mx:SWFLoader
source="C:/myProjectFolder/renderers/Junk.swf" width="100%"
height="100%" />
</mx:WindowedApplication>
This works fine if I run the application from within Flex3,
however when I build an installer, install the application to my
windows vista system and execute it from the desktop the Junk.swf
will not display. If I replace the Junk.swf with another SWF of the
same name created in Flash CS3 then it will display properly when
my test app is executed from either Flex or the desktop.
The contents of the loaded SWF don't appear to be an issue
since even the simplest of Flex3 SWFs fail to display.
Interestingly when I add listeners to the SWFLoader to
determine if any errors are happening no error events are sent, but
I do receive both the INIT and COMPLETE events which tells me that
the Junk.swf is found and loaded, just not displayed.
Any assistance or even ideas that I could try would be
appreciated.

that's why i added those comments about the swf's domain.  for locally loaded swfs, use:

Hi Kglad, Thanks for the Example.
if i run my class with securityDomain = SecurityDomain.currentDomain; then it throws this error: SecurityError: Error #2142: Security sandbox violation: local SWF files cannot use the LoaderContext.securityDomain property.
The swf file im trying to load is stored locally so i guess this error makes sense. However if i comment out that line i get the same "cannot access Stage owned by app" error?
See below for class:
package  {
  import flash.display.MovieClip;
  import flash.filesystem.File;
  import flash.events.Event;
  import flash.net.FileReference;
  import flash.events.MouseEvent;
  import flash.display.Loader;
  import flash.net.URLRequest;
  import flash.system.LoaderContext;
  import flash.system.ApplicationDomain;
  import flash.system.SecurityDomain;
  public class assetPreview extends MovieClip {
  private var loader:Loader;
  private var mainSWF:MovieClip = new MovieClip();
  public function assetPreview() {
  addEventListener(Event.ADDED_TO_STAGE, initialise);
  public function initialise(e:Event):void
  removeEventListener(Event.ADDED_TO_STAGE, initialise);
  var allowSWF:LoaderContext = new LoaderContext(false,ApplicationDomain.currentDomain);
// allowSWF.securityDomain = SecurityDomain.currentDomain;
  loader = new Loader();
  loader.load( new URLRequest(settingsXML.pathToSWF),allowSWF);
  loader.contentLoaderInfo.addEventListener(Event.COMPLETE, viewPreview);
  public function viewPreview(e:Event):void
  addChild(mainSWF);
  mainSWF.addChild(loader);
