Macromedia Flash Player vs Adobe Flash Player

adobe flash player and macromedia flash player are interchangeable terms.

You indicate you are on Windows Sever 2012, but you don't indicate which browser you are referring to, nor which Flash Player type (e.g. ActiveX Control for IE/Edge, NPAPI for Firefox, PPAPI for Chromium-based browsers) so my reply will reference these 3 player types.

19.0.0.226 is a very old version of Flash Player, released October 16, 2015.  22.0.0.210 is the most recent version of Flash Player for IE, 22.0.0.209 is the most recent version for NPAPI and PPAPI based browsers.  See http://www.adobe.com/products/flash/about for the latest versions for each supported platform.

If the versions you are referring to is for either the NPAPI or PPAPI plugin, run the Flash Player uninstaller to completely remove the plugin from your system and then go to https://get.adobe.com/flashplayer to download and install the latest version.

If the versions you are referring to are for the ActiveX Control it can indicate that Microsoft didn't completely remove the old version when it installed the update to the latest version. Since Microsoft embeds Flash Player in IE/Edge in Windows 8 and above (including Server 2012), to my knowledge, there is nothing you can do to remove the reference to the old version.  Just ensure that the browser detects the new version.  Note that the Flash Player uninstaller does not remove the embedded version of Flash Player.

To verify which version you currently have installed, launch the browser and navigate to https://helpx.adobe.com/flash-player.html and click the 'check now' button.  The widget will obtain the OS, browser, and Flash Player version, if installed, and display it.  Repeat for each browser you use, as different browsers may use different player types.
