I have installed the Flash Player from Chrome when I try to open it doesn't work
any suggestions regarding that.
Which operating system?
See the Flash Player end of life notice:
Chrome still supports Flash Player until Flash Player's end-of-life at the end of 2020. Google does disable/block Flash by default. See https://support.google.com/chrome/answer/6258784 for assistance.
Per Google's Chromium Road-map, Google will be removing support for Flash Player in Chrome version 88
