@Jeff, your answer is not correct and it shouldn't be marked as the solution. Simply quitting the CC app doesn't stop the pop-up. It is a combination of steps that must be performed and someone should document the necessary steps and list here for the official answer.
And no, someone shouldn't have to create a brand new admin user on the machine to get an annoying pop-up to stop showing. It's Adobe's bug. Don't make your users jump through unnecesarry hoops to try and fix it.
