Clean Corrupted Silverlight Installation in Windows

Silverlight is a free plug-in, powered by .NET framework and works with most web browsers, devices, and operating systems. It is a useful application that creates engaging, interactive user experiences for Web and mobile applications.

If you face difficulties while installing, uninstalling, or re-installing Silverlight, or even after installing it, Microsoft Silverlight does not work as expected, then this post is sure to help you. Before you start you may want to find out a few things!

Do I have Silverlight installed?

You can type Silverlight in Start Screen search. If it is installed you will see it as a search result. You can also fire up your browser and check in the add ons or plugins section.

Which version of Silverlight is installed?

The Silverlight runtime does not offer a simple way to find the full Silverlight version number of the installed plugin from JavaScript. It only offers a way to detect if the installed version is “at least” a particular version. But you can visit this website to find out which version of Silverlight, your computer has installed.

Website keeps asking me to install Silverlight

If some website keeps asking you to install Silverlight or update to its latest version, even if you have already done so, then open your browsers add ons or plugins manager and check if Silverlight is Enabled. If it is already Enabled, then maybe you do have a corrupted Silverlight installation, and you may need to reinstall Silverlight.
