    "Installation file is damaged" when installing an AIR supported app

      "Sorry an error has occurred.


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


      This is the message I get every time I try to install an AIR supported app.


      In the log files, I see "Got an unexpected fatal error while unpackaging: [ErrorEvent type="error" bubbles=false cancelable=false eventPhase=2 text="invalid package signature" errorID=5022]"


      The app is a bit old (2012 i think). I have the latest version of Adobe AIR as of this writing (downloaded, and installed today), system time is correct, and the .air file is being run from my local hard drive.


      Anything I can do short of setting my clock to an earlier date, or completely reinstalling Windows?


      I see this as a common issue with many threads. The only work arounds/solutions I've seen don't seem to work, or involve changing my date, or reinstalling windows.
