Try a new simple AIR app and see if it works.
I have tried that but no look?
Any other suggestions?
Is there a way that I can see what the problem with the AIR file is?
Upgraded Air SDK or installed a new AIR runtime recently?
No I didn't upgrade anything but managed to figure out what was causing the issue, I had a particular png image in my projects assets folder that seemed to be the culprit. One I removed it the app installs just fine? Really weird?
Thanks for the suggestions tho
