Windows 10-says I need to install. When I try, it says it is installed. When I test it shows disabled. When I check (thru settings and advance settings) it shows Flash Player is on. Why is it on but disabled?

If I go to a page using Flash Player, Windows 10 says I need to install it. I press install, and it says it's already on Windows 10. I press test, and it says disabled. I check on settings and advance settings, and it shows the flash player is on. I refresh the page, and it still shows as disabled. Is there some way it is both on, and disabled?
