OS:
Windows 10 Enterprise (Licensed).

Selenium Version: 2.53.0

Browser: Chrome (using chromedriver.exe)

I am using chrome to run selenium scripts. I am getting Unreachable browserException when am using driver.quit() but am not getting the error while I am using driver.close(). I checked many places over the internet for a solution, I saw in many places suggesting driver.quit() but it never worked in my environment. driver.close() always worked for me. Please let me know the way it is occurring.

2.53 is rather old, this issue (inability to find killall utility) had been fixed in later versions, please upgrade to the latest version (3.13 at the moment).
