To know which version of Flash Player you have installed on your PC, all you have to do is go to Adobe’s official help page and perform a small test. In this test you can check if you have Flash Player installed, and if so what version you have. As you see my version of flash is the 184.108.40.206, but the most recent is the .226. You can see also by right-clicking on any Flash animation. In the "About" menu option you will see the version number. From this page, or from an external source, you can upgrade to the latest version of Flash, although Windows 10’s Edge, Google Chrome, and other browsers integrate Flash by default and do not need to install it.
