Download the offline installer here: http://fpdownload.macromedia.com/get/flashplayer/current/licensing/mac /install_flash_player_12_osx.dmg

 

If it won't download directly, right click and "Save as"… and make note of the save location

DO NOT mount the installer DMG or run the installer yet!


Empty the trash

 

Reboot (this will "kill" all running processes)

 

Quit your Browser (Press Cmd+Q - Don't just close the window)

 

Go to: Mac HD/Library/Internet Plugins

 

Verify that the Flash Player.plugin file is not present.  If it is, trash it.
