If you see an error when you access Silverlight pages - then follow the info, below, to make changes to your EP configuration file.

The browser dialog window asking you to download or save the file just means that this check passed ok.

If not - please download this text file then rename it to "AddMimeTypes.vbs" and run it on a server with IIS. You should be a server administrator in order to be able to run this file.

You can check if the services work by opening an URL like that:
