Required Configuration

    On IE 7 or higher on Windows Vista or Windows 7, you must set the Protected Mode settings for each zone to be the same value. The value can be on or off, as long as it is the same for every zone. To set the Protected Mode settings, choose "Internet Options..." from the Tools menu, and click on the Security tab. For each zone, there will be a check box at the bottom of the tab labeled "Enable Protected Mode".
    The browser zoom level must be set to 100% so that the native mouse events can be set to the correct coordinates.

Even if it does not start the browser, create a desired capabilities instance and set ingnore flakiness boolean to true. Here is the code for code for ignoring the the protected mode security for all zones.
   
    DesiredCapabilities capabilities = DesiredCapabilities.internetExplorer();
 capabilities.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS, true);
        WebDriver driver = new InternetExplorerDriver(capabilities);
