    The error message here is usually a sign that you are running a 3rd party firewall or security software and it is blocking Fiddler's ability to listen on its default port.

    If you are not running a firewall that you can configure, you might try moving Fiddler to a different port (Tools > Fiddler Options > Connections) and also ensuring that you have the latest updates for .NET and Windows installed from Windows Update.

    thanks,
