title: Selenium server throws error when attempting to run test with chrome or Internet Explorer
body: <p>I have a python webdriver script which successfully runs the test on the remote server using firefox, however it throws an error when using chrome and internet explorer.</p>
  
  <p>I have added the directory with both drivers to the server's path. I have also tried starting the server using: 
  java -jar .\selenium-server-standalone-2.45.0.jar -Dwebdriver.ie.driver=.\IEDriverServer.exe -role hub </p>
  
  <p>I consistently get the same error in powershell:</p>
  
  <p>"... - Exception: The path to the driver executable must be set by the webdriver.chrome.driver system property;..."</p>
  
  <p>Working Script:</p>
  
  <pre><code>def setUp(self):
      self.wd = webdriver.Remote(
          desired_capabilities=DesiredCapabilities.FIREFOX)
  </code></pre>
  
  <p>Throws Error:</p>
  
  <pre><code>def setUp(self):
      self.wd = webdriver.Remote(
          desired_capabilities=DesiredCapabilities.CHROME)
  </code></pre>
  
  <p>What is the culprit of this problem? </p>
