silverlight is not working after macOS Sierra upgrade

I upgraded to macOS Sierra last night and now Silverlight is no longer working. The message on the web page keeps telling me to install/upgrade Silverlight but I have the latest version installed. It worked perfectly before I installed the new macOS. Any suggestions?

MacBook Pro (13-inch Mid 2012), macOS Sierra (10.12)

I just had the same problem and followed the advice (thanks to all the helpful posters) but also had to do the following: In 'Safari / Preferences / Security / Internet Plug-ins / Plug-in Settings...' click on Silverlight in the left column and underneath the right column ensure the box 'When visiting other websites' is set to ON. This solved my problem.
