Access is Denied Issue thrown at ChromeDriver Initiation step

  • Azure DevOps is triggering and running tests on a VM.

    All my tests are working fine on local machine.

    On VM, While trying to launch Chrome browser using ChromeDriver and WebDriverManager, tests are failing at LaunchChromeDriver method with failure as 'Access is Denied' at step new ChromeDriver(options);

    This is how the method looks like:

    public static IWebDriver LaunchChromeDriver()
        new WebDriverManager.DriverManager().SetUpDriver(new ChromeConfig());
        ChromeOptions options = new ChromeOptions();
        driver = new ChromeDriver(options);
        return driver;
     catch(Exception e)
     {"Exception is "+e);
        return null;

    am i missing something or do i need to modify the code ? Did anyone experienced the same ?

    Getting an exception as below:

    System.ComponentModel.Win32Exception (0x80004005): Access is denied at System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo) at OpenQA.Selenium.DriverService.Start() at OpenQA.Selenium.Remote.DriverServiceCommandExecutor.Execute(Command commandToExecute) at OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters) at OpenQA.Selenium.Remote.RemoteWebDriver.StartSession(ICapabilities desiredCapabilities) at OpenQA.Selenium.Remote.RemoteWebDriver..ctor(ICommandExecutor commandExecutor, ICapabilities desiredCapabilities) at OpenQA.Selenium.Chrome.ChromeDriver..ctor(ChromeDriverService service, ChromeOptions options, TimeSpan commandTimeout)

  • You should specify the chromedriver.exe executable file path:

    driver = webdriver.Chrome(executable_path=r"C:\Chrome\chromedriver.exe")

    For Windows, Allow Read & Execute Permissions on chromedriver.exe for Everyone:

    1. Right Click chromedriver.exe > Properties On ChromeDriver
    2. On ChromeDriver Properties Window > Security Tab, click Edit
    3. On Permissions for ChromeDriver Window > Security tab, click Add
    4. On Select Users window, set name to Everyone and click OK button
    5. On Permissions for ChromeDriver Window > Security tab, make sure Read & Execute box is checked & click OK button
    6. On ChromeDriver Properties Window, click OK button

    enter image description here

    For Linux:

    1. Check you have installed latest version of chrome browser-> "chromium-browser -version"
    2. If not, install latest version of chrome "sudo apt-get install chromium-browser"
    3. Get the appropriate version of chrome driver from
    4. Unzip the
    5. Move the file to /usr/bin directory sudo mv chromedriver /usr/bin
    6. Goto /usr/bin directory and you would need to run something like "chmod a+x chromedriver" to mark it executable.
    7. finally you can execute the code.
