Gives 'upgrade your flashplayer' message always

I am using Windows 10, with Microsoft edge as internet browser. When I am opening nseindia.com site, searching for stock, then trying to open intraday chart, I always get the message ''you need to upgrade your flashplayer''/ I tried all methods shown on internet, but nothing has worked. This is happening since about 15 days.Since that time I am struggling, somebody pl help. My e mail id is bsgadodia@gmail.com

Thanks
