Haven't had much luck myself with AIR 2.0 in Flashbuilder 4.5.1 Flex SDK overlay.
Program compiles and runs fine but the ApplicationUpdaterUI fails when it comes to comparing the update namespace descriptor and version.
Both are supposed to be the same - and 3.0 - in the -app.mxml and the update.mxml.
But something else is missing
Didn't affect my program but I don't do any video - I'd bet you might also need to
download and rename the addition runtime programs for Flash 11
and place them in a new folder under the sdk "runtimes\player\11.0"
- there should be a subfolder for win/mac/lnx under that - if you feel like downloading all the versions
For example in the runtimes\player\win folder I would suggest downloading and renaming...
1. http://fpdownload.macromedia.com/pub/flashplayer/updaters/11/flashplayer_11_ax_debug_32bit .exe ===> FlashPlayerDebugger.exe
2. http://fpdownload.macromedia.com/pub/flashplayer/updaters/11/flashplayer_11_plugin_debug_3 2bit.exe ===> InstallPlugin.exe
If you're using Windoze like I am, Jeff pointed me to this excellent post with some extra steps you might have missed.
I'm going to try it myself to see if it fixes my ApplicationUpdater issue.
I having the same problem on my App. Crash on Debug or Air.
Same problem? Did you try an Air overlay?
Yes, i overlay AIR, evething work on Mac and Linux, but on windows aways Crash ... Maybe Toninght i discovery what is crashing, i think is when i save and load my local files on my app. I will shure tomorow.
Sorry about my english.
