• Unfortunately, the Google Play cannot provide you with Flash Player. You can however get it from the archived version on the Adobre website (https://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html). 
  • Install it after downloading. Make sure to turn on the unknown sources in the Security settings if you don't have it on yet. 
  • The next thing you should do is to adjust the appropriate browser. Note that Google Chrome doesn't support this version any more.
  • The best browser is Firefox which will recognize this plugin and inform you to update it. In order to activate it, click on the information on the grey field (which should be "click here to activate the plugin").Now it should be ready. Enjoy!
