I'm about to run another pressing of CD ROMs (w/AIR-based application) and trying to determine if I need to buy a NEW digitial security certificate.
The existing certificate dosen't expire until Nov of 2012. My understanding/assumption is that when the certificate expires in Nov of 2012 users will no longer be able to install from the CD ROM. My application is strictly desktop and doesn't access the web.
I appologize in advance to forum because I know these is common topic - but I'm really confused and would appreciate any help.
I think I have discovered the answer:
If the original publisher added/included a timestamp to the installers - the installer and application should continue to work without issue. Even once passed the certificate expiration date, the installers should work fine.
If no timestamp was included then the installers will expire and no longer work past the expiration date. Users will seeing an error message similar to: 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 was able to validate this by running tests locally and advancing the time/date on a couple of different computers.
