Microsoft Silverlight is a powerful development tool and available as a plug-in for web browsers on Windows and Mac OS. It is similar to those of Adobe Flash that works fine on my Surface RT tablet. When I try to play video powered by Silverlight 5 in many websites like Comcast on IE 10, it doesn’t work at all. How can I get it working?
Internet Explorer 10 in Surface Windows RT doesn’t support any browser add-ons like Silverlight, so it is no way to add it into Windows RT unless add it as programs through the Windows Store.
This is really a particular frustration. Microsoft want to control applications through Store, so it lose the flexibility. Hope they comeback Silverlight feature.
As a Microsoft program, you can not still run Microsoft Silverlight under RT 8.1. Becasue Internet Explorer 11 in Windows RT 8.1 does not support any browser add-ons and it is also not available in the Windows Store.. So it is not way to view business related video.
Another way to resolve the problem is to buy a Surface Pro. After upgrading it to Windows 10 Pro, it is easy to get Microsoft Silverlight for watch Comcast and other videos from internet.
* The built-in Microsoft Edge finally gets add-ons and you can install the related extensions in browser, as well as the Internet Explorer also offers the option for that.
* Mozilla Firefox is compatible with NPAPI plug-ins, but prevents Silverlight plug-ins from running automatically. Just click on the Allow Now button to run it.
