AIR

I was trying to install an AIR app I’m working on, and during the install process kept getting hit with this error:

The application could not be installed because the AIR file is damaged. Try obtaining a new AIR file from the application author.

I tried a few solutions I came across (one involving deleting the /var/folders/zzz directory and rebooting, and another about building an .airi file and including that), but they didin’t work. What did work for me was to simply un-check the “timestamp option” when exporting a digital certificate during the export release build process.

The solution, along with a few others people were having was found here.
