selenium does not find firefox default installation

[jimmymain]

I have a question on stack overflow that has been unanswered for some time, there is a bug in the latest release.

My selenium tests are all failing on initalisation with this error.
{"The system cannot find the file specified"}

My initialisation code is really simple:

    public static class Host
    {
        private static readonly SelenoHost SelenoHost = new SelenoHost();
        static Host()
        {
            Instance.Run(
                configure => configure
                    .UsingLoggerFactory(new ConsoleFactory())
                    .WithWebServer(new InternetWebServer("http://localhost:9000/")));

            Instance.Application.Browser.Manage().Window.Size = new Size(1500, 1000);
        }
        public static SelenoHost Instance => SelenoHost;
    }
}

Firefox is installed in the default location, (C:\Program Files (x86)\Mozilla Firefox\firefox.exe) and is updated to the latest version (42). I am using Windows 10 Operating System.

I am using studio 2015.1

Is there some way to specify this? This used to work just fine, and I am not sure what action to take to resolve it.

If it helps, this is the stack trace.
