This is my attempt to future-proof a tutorial process for updating Flash Pro CS6. My hope is that this guide can work for the next several versions of the Flash Player. In this example I’m moving up from Flash Player 17 to version 18.
This method may work with Flash Pro CC or Flash Pro 5.5 as well (I’m not running those versions, but let me know if you try it). At the time I wrote this up I was running Windows 7, but this process may also work on Windows 8 or 10 (let me know if you try!)
