I have the same problem, when packing (FlashPlayer 10.2) for BlackBerry PlayBook:
error 305: Intial window content SWF version 11 exceeds namespace version http://ns.adobe.com/air/application/2.5
I am using Flex SDK 2.6, AIR 3.1.0 SDK and FlashDevelop 4.0.1 under Windows 7 64-bit.
Hi Dave ,
Some information about the error -
Initial window content SWF version exceeds namespace version
The SWF version of the file referenced in the <content> element of the application descriptor is not supported by the version of AIR specified in the descriptor namespace. For example, attempting to package a SWF10 (Flash Player 10) file as the initial content of an AIR 1.1 application will generate this error.
This issue is due to incorrectly configured application descriptor file.
Let me know if this helps.
Thanks and regards,
Adobe Flash Professional Team.
For me, this issue was caused by corrupted files. I blew the files away (rm -rf), re-downloaded them from the repository and it worked.
