Just ran into this today. I was compiling an AIR application and previewing it in AIR Debug Launcher and got the following error:

“invalid application descriptor: descriptor version does not match runtime version”

If you look at the top of your application descriptor XML file, you’ll see the application namespace… something like this:

That “1.5″ is the version of ADL the descriptor is looking for. To see what version you have, go to your Flex SDK directory and look in “bin”. On Windows, right-click on “adl.exe”, go to “Properties” and click on the “Version” tab. There, you’ll see the ADL version number — make sure that the number in your descriptor file matches this, both the major (x.0) and the minor number (o.x).
