Disply unity build in flex

We have tried the following methods to upload sample Unity3D build to desktop application in flex:HTML Loader, NavigateToURL, iFrame & resolvePath but it only display the text content not the 3D content. What is the solution for that? Here I attach the print screen of our output.

From the API documentation for HTMLLoader @ Adobe:

On desktop computers (in the desktop and extended desktop profiles), the HTMLLoader class uses the internal AIR WebKit engine

I assume it can not find/resolve the unity web player plugin that doesn’t support your setup.

From the webplayer download page:

UNITY WEB PLAYER FOR WINDOWS
Internet Explorer, Firefox, Chrome, Safari, Opera

There isn’t any mention of Webkit compatible software.
