    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.
