My AIR app was recently distributed and was only self-signed
at the time. We then decided to sign the very same application, but
now the auto-updater fails with a 'misconfigured installer' error
message. Is there any way to make this transition seamless for
users with self-signed version? Clearly, I would like to avoid
having to explain to the user how to uninstall the application
before downloading the update. Thanks for your time!
