Following a tutorial here.

Code is as follows...

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using OpenQA.Selenium;
using OpenQA.Selenium.IE;
using OpenQA.Selenium.Support.UI;

namespace mySelenium
    class Program
        static void Main(string[] args)
            IWebDriver driver = new InternetExplorerDriver(@"C:\Downloads\selenium");

When I run the code all seems to go well, an instance of internet explorer starts and it tries to navigate to google, except I get the message...

This page can’t be displayed

•Make sure the web address is correct.
•Look for the page with your search engine.
•Refresh the page in a few minutes.

IE works fine when I run it manually.

Anyone had this before can offer any help?

Seems it was a firewall issue with IEDriverServer.exe.

Appears to be fine now.
