WebDriverException: unknown error: cannot find Chrome binary error with Selenium in Python for older versions of Google Chrome
Question:
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 https://www.slimjet.com/chrome/google-chrome-old-version.php and Chromedriver 2.26 from https://chromedriver.storage.googleapis.com/index.html?path=2.26/.
I am using the following code to attempt to set my Chrome binary location:
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)
However, when I attempt to launch the WebDriver Python returns the following error:
WebDriverException: unknown error: cannot find Chrome binary
(Driver info: chromedriver=2.26.436362
(5476ec6bf7ccbada1734a0cdec7d570bb042aa30),platform=Windows NT 10.0.14393 x86_64)
I have tried searching through similar questions and answers, but have not had any luck so far.

You can specify the binary path in the constructor of the webdriver:
driver = webdriver.Chrome('/path/to/chromedriver') # Optional argument, if not specified will search path.
This error message…
WebDriverException: unknown error: cannot find Chrome binary
…implies that the ChromeDriver was unable to find the Chrome binary in the default location for your system.
As per the ChromeDriver – Requirements:
The server expects you to have Chrome installed in the default location for each system:
OS
Expected Location of Chrome
Linux
/usr/bin/google-chrome1
Mac
/Applications/Google Chrome.app/Contents/MacOS/Google Chrome
Windows XP
%HOMEPATH%Local SettingsApplication DataGoogleChromeApplicationchrome.exe
Windows Vista and newer
C:Users%USERNAME%AppDataLocalGoogleChromeApplicationchrome.exe
1 For Linux systems, the ChromeDriver expects /usr/bin/google-chrome to be a symlink to the actual Chrome binary.
Using a Chrome executable in a non-standard location
However you can also override the default Chrome binary location as follows:
To use Chrome version 55.x installed in non standard location through ChromeDriver v2.26 you can use the following 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(chrome_options = options, executable_path=r'C:pathtochromedriver.exe')
driver.get('http://google.com/')
print("Chrome Browser Invoked")
driver.quit()

I faced similar issue in MacOS. Even after setting binary path in chromeoptions, it didn’t work. It got fixed after installing npm i chromedriver
What happened to me is that I didn’t have chrome, the main browser, installed.
Download the browser and it fixes this issue.
Using an old version of chrome driver with the latest Google Chrome locally gave me the same exception.
Just go to the ChromeDriver page and make sure you have the latest version.
I did this to solve my problem
private WebDriver driver;
@Before
public void StartBrowser() {
System.setProperty("webdriver.chrome.driver", "C://opt//WebDriver//bin//chromedriver.exe");
driver = new ChromeDriver();
driver.get("https://www.saucedemo.com/");}
I have solved this problem by installing Google Chrome link and it solved problem automatically (I use Kali Linux) and be sure that it is installed to the "/usr/bin"(default it is downloaded to here).
It is also important to download Chrome from the actual website. I ran into the same problem, but I had downloaded Chrome from the Ubuntu software package manager. I uninstalled the package manager version and installed from the website, and the error resolved. Same issue could probably arise installing from other package managers.
I faced this error because i installed Chrome with flatpak then Selenium doesn’t find the directory of the Driver. Then i installed Chrome with Fedora Store and fixed.
I think this is the easiest way;
Download chromedriver and chrome version [except 115.0.5790.110 (it does not work properly)] from this link : chrome-for-testing.
- Put the chrome driver in the chrome path
- Replace the below path with your Chrome version path
from selenium import webdriver
options = webdriver.ChromeOptions()
options.binary_location = "C:/Program Files/Google/Chrome Dev/Application/chrome.exe"
driver = webdriver.Chrome(options=options)
#################
driver.get('https://realpython.com/openpyxl-excel-spreadsheets-python/')
On Mac, there is a new bug causing the same error even if Chrome is installed at the default place. This is because the new chromedriver is looking for "Google Chrome for Testing.app" instead.
I did the following:
mkdir foo
cd foo
npx @puppeteer/browsers install chrome@stable
mv chrome/mac-115.0.5790.102/chrome-mac-x64/Google Chrome for Testing.app /Applications
rm -rf chrome
Update: The latest version seems to be fixed now.
