Install Adobe Flash 10

Flash

Some websites might require, but you can enable it on demand if required by clicking the puzzle icon in the Edge Address bar.

Updates for Flash Player in Microsoft Edge is handled through Windows Update. So, the first thing I would recommend you do is check Windows Update for updates for Flash.
Open Start > Settings > Update & security > Windows Update > Check for updates.
Download any important updates that might be available.
Restart, then try loading the web page again.
In Edge, click the More actions menu in the top right hand corner represented by the three dots.
Click Settings > Advanced Settings then toggle on Use Adobe Flash Player - if its already on - toggle it off, restart Edge then toggle it on again.
When you visit a web page that requires Flash Player, make sure to look in the Address bar for a puzzle icon. Click it and it should offer the option to load Flash once or always.
If that does not work, try resetting or repair Edge:
