Answer 1

You need to change :
System.setProperty("WebDriver.gecko.driver","C:/geckoDriver.exe");
To :
System.setProperty("webdriver.gecko.driver","C:/geckodriver.exe");
In Selenium 3.x the Key-Value pair is expressed as webdriver.gecko.driver and C:/geckoDriver.exe

Answer 2

Try with updating code:
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class AadminLogin {
public static void main(String[] args) {
// TODO Auto-generated method stub
System.setProperty("webdriver.gecko.driver","C:/geckodriver.exe"); //Here changes are made
WebDriver driver= new FirefoxDriver();
driver.get("http://www.gmail.com");
driver.findElement(By.id("Email")).sendKeys("Kawal");`
}
}
All other things are fine. it is just some casing issue in setProperty(). And for 2.53 there is no need of geckodriver
