Silverlight Application

We have a silverlight web application, and I’ve tried to browse to it on the HTMLViewer control, and it doesn’t have the silverlight extension enabled in it… using OSX 2015r4 - any ideas? Can I add support somehow?

I encounter a similar issue - couldn’t get a website that requires silverlight to work. Any solution?

I know the docs state that for Windows, I wonder if the same applies for macOS?

Silverlight is dead. It may be time to impress the boss and write a replacement web app?

Looks like the plugin is already in the right place but it just didn’t work somehow. The htmlviewer only showed “Plug-in Failure” in the center when launched. See report below:

I have no choice but to accept using silverlight because of the website I’ve been trying to access: http://www.freestockcharts.com/platform/v1

Looks like a dead end…?!

[quote]With the last updates Silverlight is not allowed to access the local files(anymore).
Unchecking the ‘Run in Safe Mode’ option at the Preferences>Websites>Plugins>Silverlight for your configured Website did the trick for us.
By default, this option is hidden, hold down the option key while clicking the drop down next to your website to change it.[/quote]

Thank you, Dave, for the suggestion which I followed to the T to uncheck “Run in Safe Mode” in Safari Plugin/Silverlight. However, still no luck - error report below.

The funny thing is, Silverlight runs okay on the target website regardless of the status of “Run in Safe Mode”. However, when a htmlviewer in Xojo trying to access the same website, the plugin failure occurred.
