title: WebDriverException: unknown error: cannot find Chrome binary error with Selenium in Python for older versions of Google Chrome
body: <p>For compatibility reasons I prefer to use Chrome version 55.0.2883.75 with Chromedriver v. 2.26. I downloaded the older version of chrome from <a href="https://www.slimjet.com/chrome/google-chrome-old-version.php" rel="noreferrer">https://www.slimjet.com/chrome/google-chrome-old-version.php</a> and Chromedriver 2.26 from <a href="https://chromedriver.storage.googleapis.com/index.html?path=2.26/" rel="noreferrer">https://chromedriver.storage.googleapis.com/index.html?path=2.26/</a>.</p>
  
  <p>I am using the following code to attempt to set my Chrome binary location:</p>
  
  <pre><code>from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  
  options = Options()
  options.binary_location = "C:\\Program Files\\Chrome\\chrome64_55.0.2883.75\\chrome.exe"
  driver = webdriver.Chrome('chromedriver.exe', chrome_options = options)
  </code></pre>
  
  <p>However, when I attempt to launch the WebDriver Python returns the following error:</p>
  
  <pre><code>WebDriverException: unknown error: cannot find Chrome binary
  (Driver info: chromedriver=2.26.436362
  (5476ec6bf7ccbada1734a0cdec7d570bb042aa30),platform=Windows NT 10.0.14393 x86_64)
  </code></pre>
