Problem in launching an installed or launch AIR application from the browser.

I am trying to launch or install my AIR application using launchApplication() in air.swf API . I am getting runtime error for both launch or install AIR application from browser.

Error: Invalid argument: [Event type="init" bubbles=false cancelable=false eventPhase=2]
     at AIR$/escapeArguments()
     at AIR/launchApplication() 

To launch or install AIR application I am referring following link:

http://livedocs.adobe.com/flex/3/html/help.html?content=distributing_apps_3.html

I have kept browser invocation feature as true in the application descriptor file in order to launch air application.

<allowBrowserInvocation>true</allowBrowserInvocation>
But it still doesn't work form me.

Kindly advice on this.

Thanks,

Sanjay
