invalid application descriptor: Unknown namespace: http://ns.adobe.com/air/application/3.6

I'm using Flash Builder 4.7.

I've replaced the AIRSDK folder with the latest version. Restarted Flash Builder and updated the application XML file to set the namespace to 3.6.

I get the following error when I try to test or publish my app.

Process terminated without establishing connection to debugger.

invalid application descriptor: Unknown namespace: http://ns.adobe.com/air/application/3.6

Launch command details:  "/Applications/Adobe Flash Builder 4.7/sdks/4.6.0/bin/adl" -runtime "/Applications/Adobe Flash Builder 4.7/sdks/4.6.0/runtimes/air/mac" -profile mobileDevice -screensize 320x460:320x480 -XscreenDPI 163 -XversionPlatform IOS "/Users/me/Documents/Adobe Flash Builder 4.7/MyAppMobileApp/bin-debug/MyAppMobile-app.xml" "/Users/me/Documents/Adobe Flash Builder 4.7/MyAppMobileApp/bin-debug"

If I set the namespace to 3.1 it works but then I can't Export a Release build because of the default launch images needed for iOS.

I overlayed the AIR SDK many times in Flash Builder 4.6 but there seems to have been a folder change in Flash Builder 4.7.
