Get Microsoft Silverlight  
If you have problems installing Silverlight…
FireFox Support: On Windows 10:
Starting with version 52 (March 2017) Firefox stopped supporting Silverlight.
To use EPPI-Reviewer in Firefox (both Mac and Windows), you can use the Firefox ESR distribution. Firefox ESR is a release pathway optimised for stability and is therefore preferred in many business environments. Naturally, security isn't compromised, while stability is enhanced.
We are in the process of writing the next version of EPPI-Reviewer, which will run in a normal browser (without needing any plug-in).
In the mean time, EPPI-Reviewer can still be used on Macs (Safari and Firefox ESR) and Windows (Internet Explorer and Firefox ESR).
More information is here.
The new Edge browser does not support Silverlight. However, Internet Explorer is present in all Windows 10 machines:
1. Type "Internet Explorer" in the Cortana/Search box.
2. Right click on the "Internet Explorer" result.
3. To add as a tile on your Start Menu click "Pin to Start."
4. To keep it on your taskbar click "Pin to taskbar."
If the above doesn't work, you may need to enable the "Internet Explorer" feature, this is done via "Control panel\Programs\Programs and Features" and "Turn Windows features on or off".
