Adobe flash player has changed pop up

Hello - I have about 500 users who are getting the attached message.  we recently did some updates, flash player one of them, and users now get the attached message.  What can be done to prevent this message from popping up again.  (getting 500 tickets from people who cannot read the message and see what it is asking is too much)

Is this a new feature because we update flash all the time and have never received this message.
