I am using the chrome webdriver for a project which works well when I run it on my local pc, however when I uploaded the project to my remote server for it to run live, the chromedriver could not load:
this is how I am calling my chromedriver:
IWebDriver driver = new ChromeDriver(#"C:\Users\User\Downloads\chromedriver_win_26.0.1383.0");
this is the error I get:
Could not find default Chrome binary
I have made sure that:
the chromedriver.exe actually is in the specified location on the server
I upload the dlls needed for it to run
Any ideas please as to why this is happening?
The WebDriver part is fine, but I found that the problem is that the code can't find Chrome.exe itself.
It should be installed in this folder:
C:\Users\%USERNAME%\AppData\Local\Google\Chrome\Application\chrome.exe
Please check this on Requirements: http://code.google.com/p/selenium/wiki/ChromeDriver
P.s: I tested myself and it works now. :)

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. Any help is greatly appreciated - thank you in advance!
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 Settings\Application Data\Google\Chrome\Application\chrome.exe
Windows Vista and newer
C:\Users%USERNAME%\AppData\Local\Google\Chrome\Application\chrome.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:\path\to\chromedriver.exe')
driver.get('http://google.com/')
print("Chrome Browser Invoked")
driver.quit()

You can find a detailed discussion in:
Is Chrome installation needed or only chromedriver when using Selenium?
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 faced similar issue in MacOS. Even after setting binary path in chromeoptions, it didn't work. It got fixed after installing npm i chromedriver
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.
Check https://sites.google.com/a/chromium.org/chromedriver/getting-started
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.
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).
when i go to command prompt and type chromedriver -v:
ChromeDriver 79.0.3945.36 (3582db32b33893869b8c1339e8f4d9ed1816f143-refs/branch-heads/3945#{#614})
but when i try to run this code :
from selenium import webdriver
class InstaBot:
def __init__(self):
self.driver=webdriver.Chrome()
self.driver.get("www.instagram.com")
InstaBot()
it gives me error like this:
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 80
why this is happening i tried to remove selenium as well as chromedriver
and reinstall of version 79.0.3945 but when i run it ,it show this can only be run on version 80
my chrome version is 79.0.3945 which is lastest ,and version 80 chrome is chrome beta
This error message...
selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 80
...implies that the ChromeDriver v80.0 was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser session.
Your main issue is the incompatibility between the version of the binaries you are using as follows:
You mentioned about using chromedriver=79.0.3945.36 and the release notes of chromedriver=79.0 clearly mentions the following :
Supports Chrome v79
Presumably you are using chrome v79.0 browser.
So, it's quite evident your have chromedriver=80.0 present within your system which is also within the system PATH variable and is invoked while you:
self.driver=webdriver.Chrome()
Solution
There are two solutions:
Either you upgrade chrome to Chrome Version 80.0 level. (as per ChromeDriver v80.0 release notes)
Or you can override the default chromedriver v80.0 binary location with chromedriver v79.0 binary location as follows:
from selenium import webdriver
driver = webdriver.Chrome(executable_path=r'C:\path\to\chromedriver.exe')
driver.get('http://google.com/')
You can find a detailed discussion in Ubuntu: selenium.common.exceptions: session not created: This version of ChromeDriver only supports Chrome version 79
Additional Considerations
Ensure to:
Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
Take a System Reboot.
Execute your #Test as non-root user.
Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.

I have written an automation framework in VS2017 using Selenium Webdriver in C# and PageObjects. That is working absolutely fine in windows. Same PageObjects code is used in VS2017 for MAC OS and it is not working there giving
OpenQA.Selenium.NoSuchElementException : Couldn't locate an element by these strategies: By.Id: userNameInput;
----> OpenQA.Selenium.WebDriverTimeoutException : Timed out after 1 seconds
I have moved my code from VS2017 For Windows to VS2017 for Mac. That is successfully converted and compiled. There were problems however i have resolved the webdriver related issues and now code is working perfectly to Launch Chrome & Safari. But whenever i try to find elements, the exception occurs. I have implemented Explicitwaits and other parameters but both Safari and Chrome are giving me errors at some stage in finding the elements. I have also tried finding the elements without POM but that doesn't work too.
Considering the following function i have written to Signout user from Dynamics CRM
public void UserSignOut(ref ExtentTest test)
{
WDEx.SwitchWindows(0);
Browser.Driver.SwitchTo().DefaultContent();
UserIcon.Click();
SignOut.Click();
}
where
UserIcon is
[FindsBy(How = How.Id, Using = #"navTabButtonChangeProfileImageLink")]
public IWebElement UserIcon { get; set; }
and SignOut is
[FindsBy(How = How.Id, Using = "navTabButtonUserInfoSignOutId")]
private IWebElement SignOut { get; set; }
It should work exactly the way as it is working on Windows Chromedriver with VS2017. If anybody could provide a solution then that could be very time saving for me. Thankful in Advance. Cheers!
I am working with c# selenium.
I am getting error with chrome driver as :
System.InvalidOperationException : disconnected: unable to connect to renderer
(Session info: chrome=62.0.3202.94)
(Driver info: chromedriver=2.32.498550

Now I tried updating the chrome browser version to 2.33 and its working fine on my local machine.
But I am getting this error my server where I am executing this tests on schedule basis.
I am using TFS to deploy tests on the server and to run the tests.
the same project is working on my local machine but I am getting this error on server for the
driver.Manage().Window.Maximize();
line for all the tests.
I check out same project from TFS on my colleagues machine and tried executing there its was working fine.
I tried updating driver to 2.33 even tried downgrading the driver to 2.32 and executed multiple time but its not working.
I am using MS build to build the automation project and deploy it on server as well.
Since it works well on your local machine，but got error when you run the tests on the server.
First make sure your server environment are the same with your local machine such as chrome browser version is 2.33 and the driver is also 2.33.
According to this code driver.Manage().Window.Maximize(); line.
Please make sure that you give enough time for the window to load before you declare this statement.
If you are finding any element to input some data then provide reasonable delay between this and the input statement.

I have faced the same problem today, It get resolved by using updated chrome driver pack 2.33.
When I am using Python 3, facing the same error, in my situation, I did not close the chrome process after using it. So you should check the chrome process properly closed after using it.
I am using selenium to test our websites. When I build the project, there is an Exception :-
OpenQA.Selenium.WebDriverException: Failed to start up
socket within 45000 milliseconds. Attempted to connect to the
following addresses: 127.0.0.1:7055 and the problem is from the code
IWebDriver driver = new FirefoxDriver();
Anybody knows how to solve this problem?
Just like the other drivers available to Selenium from other browser vendors, Mozilla has released an executable that will run alongside the browser.
You can download the latest executable geckodriver from here
Add downloaded executable geckodriver to system path
The Selenium client bindings will try to locate the geckodriver (or wires) executable from the system path. You will need to add the directory containing the executable to the system path.
On Unix systems you can do the following to append it to your system’s search path, if you’re using a bash-compatible shell:
export PATH=$PATH:/path/to/directory/of/executable/downloaded/in/previous/step
On Windows you need to update the Path system variable to add the full directory path to the executable geckodriver. The principle is the same as on Unix.
After all above stuff you need to Initialize FireFoxDriver as below :-
var driver = new FirefoxDriver(new FirefoxOptions());
Note :- Follow this link for the solution of this problem with other programming language.
This answer didn't worked with me. Running selenium 2.53.6 and firefox 47 n 48.
I would recommend downloading firefox 46 which seems to be the best match for selenium 2.53.x.
https://ftp.mozilla.org/pub/firefox/releases/46.0.1/win64/en-US/
Once I downgraded to firefox 46.0.1 everything was working as expected.
