I have a problem with silverlight. The other day it works perfectly. But since thursday it wont work. It just say that I have to install it. But I already have it. When I install it and tray to start it the program says that I already have that
version. And I can´t do anything. I have used firefox. But tryed edge and that don´t work eather. What shall I do?
Silverlight is no longer under active development. It has never worked on Edge. Firefox 52 came out a few days ago which dropped support for Silverlight and all NPAPI plugins
To get it working in Firefox you need to download the ESR version of Firefox. Details are here: https://support.mozilla.org/t5/Problems-with-add-ons-plugins-or/Why-do-Java-Silverlight-Adobe-Acrobat-and-other-plugins-no/ta-p/31069
You should also check with whatever service you are using that still has Silverlight and make sure they are working on a non-Silverlight option.
