I have downloaded the 32-bit version of geckodriver.exe and have written the following code in the .java file

System.setProperty("webdriver.gecko.driver","D:\\geckodriver.exe");
FirefoxDriver fd = new FirefoxDriver();
fd.get("http://bbc.com");
System.out.println("Application title is ============="+fd.getTitle());

I am getting the below error.Please help to launch Firefox...Thank you.

Below code working fine in FF 47 and Latest Selenium (3.0.1)

public class launchFF {

public static void main(String[] args) {






System.setProperty("webdriver.firefox.marionette","E:\\geckodriver.exe");
(Please note system property should change to above)
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);

WebDriver driver = new FirefoxDriver();

driver.get("http://www.youtube.com");

System.out.println("Made it to the promised land");

driver.quit();

}

}

However I have tried FF 49 and FF 50 with Latest Selenium but I am getting same error.
