HELP! - Can't update Adobe Air Apps - Application Install Error

I have several Adobe Air Apps on my Mac OSX (10.9.4) MackBook Pro. They won't update due to the following Install Error.

"The application cannot be installed due to a certificate problem. The certificate does not match the installed application certificate, does not support application upgrades, or is invalid. Please contact the application author."

Following the above instructions, I've been contacting the authors of my Adobe Air Apps and they are telling me that it is not their problem. The Apps should simply update without difficulty.

I searched the "Google" and found no fix other than uninstall and reinstall Adobe Air. Did this and the problem persists.

If you can help me get beyond this issue and back to productivity, I'd be very appreciative.

Thanks!

David
