I have uninstalled, and reinstalled the lastest flash player. No luck getting it to actually work in the Internet Explorer 11.
I have used all of the help info, done everything it mentions, still no luck.
I have disabled my security software, still no luck.
IE11 is a "Rolling train wreck" Hopefully this latest abomination will be what it takes for everyone to finally tell Microsoft what they can do with the garbage they call software. Thousands of sites and millions of pages can't recognize the browser, so they don't recognize any of the plugins, like Flash Player. So far, Microsoft has made NO indication that they have any plan to fix it soon.
Microsoft's recommendation is to use Compatibility View for affected pages, and "pretend" you're using an different browser. Trouble with that is it has seen limited success at best, and you have to individually enable it for EVERY page that has problems.
I'm not big on "pretending" so I recommend actually using another browser.
ANY of those will work where IE11 won't, with the Flash Player Plug-in (For all other browsers), and Chrome doesn't even need that because it has its own Flash Player plugin built in.
