Answer 1

Add these lines to your code before creating the object.

   System.setProperty("webdriver.ie.driver", 
        "E:\\path where your IEDriverServer is located\\IEDriverServer.exe");

You can download IEDriverServer.exe file from here.

As you are using C# you can use the below code.

private const string IE_DRIVER_PATH = @"C:\PathTo\IEDriverServer";
var driver = new InternetExplorerDriver(IE_DRIVER_PATH, options);
