On Windows 10 it works for me with an old Silverlight Verison (Silverlight 5 Build 5.0.61118.0 Released December 9, 2011), that you can download here: http://www.microsoft.com/getsilverlight/locale/en-us/html/Microsoft%20Silverlight%20Release%20History.htm
Maybe this helps also other users. Tested in Firefox and IE11. This version also works for me on Windows 8.1.
