Requesting BASELINE_EXTENDED profile in air 3.9 or 4.0 causes error

Just made a quick test on 3.9, Application, set to direct render of course, no issue:

package {           import flash.display.Sprite;           import flash.display.Stage3D;           import flash.display.StageAlign;           import flash.display.StageScaleMode;           import flash.display3D.Context3D;           import flash.display3D.Context3DProfile;           import flash.display3D.Context3DRenderMode;           import flash.events.ErrorEvent;           import flash.events.Event;           public class CX3D extends Sprite           {                     private var s3d:Stage3D;                     private var rc:Context3D;                     public function CX3D()                     {                               stage.align = StageAlign.TOP_LEFT;                               stage.scaleMode = StageScaleMode.NO_BORDER;                               s3d = this.stage.stage3Ds[0];                               s3d.addEventListener(Event.CONTEXT3D_CREATE, onContextF);                               s3d.addEventListener(ErrorEvent.ERROR, contextErrorF );                               s3d.requestContext3D(Context3DRenderMode.AUTO, Context3DProfile.BASELINE_EXTENDED);                     }                     private function contextErrorF(e:Event):void                     {                               trace('Error ' + e);                     }                     private function onContextF(e:Event):void                     {                               trace('Created ' + e);                               rc = Stage3D( e.target ).context3D;                trace(rc);                     }           } }

Trace:

Created [Event type="context3DCreate" bubbles=false cancelable=false eventPhase=2] [object Context3D]

(used a TextField for output in my finished .exe)

edit:

Although unlikely, if your desktop GPU is old enough it very well may not support that mode.
