Unable To Launch Firefox Driver

Question

I have checked YouTube & Google for solutions to this error. But I have not been able to get one.

Please, I get this error when I write some code to launch the Firefox driver:

An unhandled exception of type 'OpenQA.Selenium.DriverServiceNotFoundException' occurred in WebDriver.dll

Additional information: The geckodriver.exe file does not exist in the current directory or in a directory on the PATH environment variable. The driver can be downloaded at https://github.com/mozilla/geckodriver/releases.

Here is the code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;
using System.Threading.Tasks;


namespace FireFox_Driver_Launch
{
    class Program
    {
        static void Main(string[] args)
        {

            var Driver = new FirefoxDriver();
            Driver.Navigate().GoToUrl("http://www.starwoodhotels.com/preferredguest/account/enroll/index.html");

        }
    }
}

I have added the selenium webdriver package from "Manager Nuget Packages" as well.

I have searched this site & Google for a solution. But, I have not gotten a solution yet.

The firefox browser is installed on the PC.

I have downloaded the geckodriver. Please, how do I put it in the PATH?

I believe it should be in the System Environment variables ?

I have also installed Selenium.Firefox.Webdriver.

In addition, I downloaded the gecko driver & put it in the project folder. Still getting an error.

Make sure that the folder where geckodriver.exe (the one you downloaded) is located is on your systems PATH. Here's a tutorial about how to add a folder to PATH: http://www.computerhope.com/issues/ch000549.htm

First Update your Firefox Browser to the latest version.

Second you need need to download the geckodriver.exe from the below url as per your system configuration.

https://github.com/mozilla/geckodriver/releases

Third write the below code to start the Firefox Browser.

//Give the path of the geckodriver.exe    
FirefoxDriverService service = FirefoxDriverService.CreateDefaultService(@"C:\Users\abcd\Downloads\geckodriver-v0.13.0-win64","geckodriver.exe")

//Give the path of the Firefox Browser        
service.FirefoxBinaryPath = @"C:\Program Files (x86)\Mozilla Firefox\firefox.exe";

IWebDriver driver = new FirefoxDriver(service);

driver.Navigate().GoToUrl("https://www.google.com");

Note: Assumption you are running selenium 3.0.1
