I have a serious problem, I am unable to install any exported air file created in my AppTest project. I just keep getting an error saying: "Sorry, an error has occurred. The application could not be installed because the AIR file is damaged. Try obtaining a new AIR file from the application author."
I am using FlexBuilder 3 to build and export my app release build. If anyone can help me I would greatly appreciate it.
I'd try un-then-reinstalling and making sure any overlay that you're applying (update of SDKs, etc.) are done correctly.
