If you're being prompted to update at some point (a non-embedded) Flash Player was installed on the system. To find out which one is installed, do the following:

Windows: Control Panel > All Control Panel Items > Flash Player > Updates tab

Mac: System Preferences > Flash Player > Updates tab



Anything listed in the Updates tab is non-embedded version and one of these is prompting for an update (if it's older than version 32.0.0.114) If you only use Chrome, you can uninstall the non-embedded versions and use the embedded PPAPI plugin.

On Windows, use the standalone uninstaller posted at Uninstall Flash Player for Windows

On Mac, use the Adobe Flash Player Install Manager.app utility saved in /Applications/Utilities, or download the uninstaller posted at Uninstall Flash Player for Mac OS​.
