Error: Cannot start debugging. Silverlight developer runtime not set. Please install the appropriate version.

I have VS2010 and Silverlight SDK 3 and 4. I created a sample application in vs2010 using the SilverLight web application. When I press F5, an error appears: Error: Cannot start debugging. Silverlight developer runtime not set. Install the appropriate version.

Developer SDKs and Runtimes are separate things - try uninstalling Silverlight (only runtime, no need to remove SDKs, tools, etc.) and reinstall only developer runtime from here: http://go.microsoft.com/fwlink/? LinkID = 188039

An old question - but I just picked up an old Silverlight project that I grabbed and ran into this error. After uninstalling and installing various versions (I now have SDK5), the problem was that I used a version of Google Chrome 47 that is not supported (versions 42 and LATER are not supported). Micorosoft Edge is also not supported. There’s a bit of clutter at the bottom of this page: https://www.microsoft.com/getsilverlight/get-started/install/default.aspx?reason=unsupportedbrowser&_helpmsg=ChromeVersionDoesNotSupportPlugins&v=5.0.61118.0#
