A department needs access to a Silverlight application hosted here https://client.capturerx.com/cumulus
I'm moving this department from 2003 Terminal Services to 2012R2 RDS.
I installed Silverlight by downloading the silverlight 64 installer and installing it via control panel>install programs on Remote Desktop Server while logged on as administrator
As a standard user (no policies yet applied) Silverlight does not show up in IE addons, even when I select Show: All Add ons
In Firefox, the plugin is available, and configured to allow storage, but will not let a silverlight plugin cache itself or any data.
A silverlight test site seems to run OK in Firefox bubblemark .com / silverlight2 .html
I don't know what else to try. Any help is appreciated
