I have installed several adobe products that are signed with the certificate that will be revoked (including adobe flash). What would be the impact on the end users, if I font upgrade those products, when the certificate is revoked?
Please describe particularly what would happen with the flash plugin in the browsers?
Will the users be able to still use the software or the OS will prevent it from lunching?
Products which are affected should be updated. Not doing so may result in an error about the application being from an unknown publisher on launch, although the application should still launch. The Flash Player plug-in in browsers is not affected. This document might be helpful for you too.
