This question is similar to: OSError: [WinError 193] %1 is not a valid Win32 application. If you believe it’s different, please edit the question, make it clear how it’s different and/or how the answers on that question are not helpful for your problem. – Mailemailed

I have edited it with more specific code. Hope some can help me. – Audraaudras

Answer 1

If you construct the service like this:

service = ChromeService(ChromeDriverManager().install())

I noticed ChromeDriverManager().install() returns <path stuff>\chromedriver-win32\THIRD_PARTY_NOTICES.chromedriver instead of the chromedrive.exe.

This works for me:

chrome_install = ChromeDriverManager().install()

folder = os.path.dirname(chrome_install)
chromedriver_path = os.path.join(folder, "chromedriver.exe")

service = ChromeService(chromedriver_path)

Hi, in my case, which part below shall I change to make it work? options = Options() options.add_argument("--incognito") # incognito mode options.add_argument('ignore-certificate-errors') # if website have SSL error, this code will fix SSL Certificate requirement chrome_service = ChromeService(ChromeDriverManager().install()) chrome_service.creationflags = CREATE_NO_WINDOW # hide webdriver console driver = webdriver.Chrome(service=chrome_service, options=options) # ChromeDriverManager() driver.minimize_window() # minimized browser print('Chrome webdriver loaded') – Audraaudras

Replace your: chrome_service = ChromeService(ChromeDriverManager().install()) with all the lines I posted, but change service = ChromeService(chromedriver_path) to chrome_service = ChromeService(chromedriver_path) – Cornish

Everyone, I'm sure you are facing a sudden problem and are having a lot of trouble,

but it turns out that this problem can be solved by updating the version of webdriver_manager.

• My coding

import wx
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from webdriver_manager.chrome import ChromeDriverManager

# Required for dialog box display
app = wx.App(0)

# Creating options
option = Options()

# To avoid "unknown error: net::ERR_CONNECTION_CLOSED"
option.add_argument('--disable-dev-shm-usage')

option.add_argument('no-sandbox')
option.add_argument('--disable-extensions')
option.add_argument('--disable-gpu')
option.add_argument('disable-infobars')
option.add_argument('--incognito') # secret mode

# Enable headless mode.
option.add_argument('--headless')

# Create a Chrome WebDriver object.
try:

# Process to automatically install the driver of the same version as Chrome on your PC.
    driver = webdriver.Chrome(executable_path=ChromeDriverManager().install(), options=option)

except Exception as e:
    print("error:", e)
    wx.MessageBox(f'{e}', u'error', wx.ICON_ERROR)

Answer 3

chrome_options = ChromeOptions()
chrome_options.add_argument("--headless=new")
driver = webdriver.Chrome(options=chrome_options)

It works on my programme. Just delete ChromeDriverManager().install() and ChromeService.

The problem is with the newest version of webdriver (or downloader).

Look into the file: c:\Users\<user>\.wdm\drivers.json

The new version section differs from the previous. "binary_path" points to "THIRD_PARTY_NOTICES.chromedriver" instead of "chromedriver.exe"

    "win64_chromedriver_126.0.6478.127_for_126.0.6478.127": {
        "timestamp": "17/07/2024",
        "binary_path": "C:\\Users\\JohnX\\.wdm\\drivers\\chromedriver\\win64\\126.0.6478.127\\chromedriver-win32/chromedriver.exe"
    },
    "win64_chromedriver_126.0.6478.182_for_126.0.6478.182": {
        "timestamp": "24/07/2024",
        "binary_path": "C:\\Users\\JohnX\\.wdm\\drivers\\chromedriver\\win64\\126.0.6478.182\\chromedriver-win32/chromedriver.exe"
    },
    "win64_chromedriver_127.0.6533.89_for_127.0.6533.89": {
        "timestamp": "05/08/2024",
        "binary_path": "C:\\Users\\JohnX\\.wdm\\drivers\\chromedriver\\win64\\127.0.6533.89\\chromedriver-win32/THIRD_PARTY_NOTICES.chromedriver"
    }

The solution provided by asdfa works as it replaces the path. You can also try to modify "drivers.json" file.

I also came across this issue today. My setup looks like:

options = webdriver.ChromeOptions()
options.add_argument(r"user-data-dir=C:\Users\usr\AppData\Local\Google\Chrome\User Data")
options.add_argument(r'--profile-directory=Profile 1')

driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=options) 

I get a similar error: OSError: [WinError 193] %1 is not a valid Win32 application when calling webdriver.Chrome() The code block was working fine just 18 days ago, but something must have changed.

This error was fixed using asdfa's solution by creating the service (path to driver exe) separately like so:

chrome_install = ChromeDriverManager().install()
folder = os.path.dirname(chrome_install)
chromedriver_path = os.path.join(folder, "chromedriver.exe")
service = webdriver.ChromeService(chromedriver_path)

options = webdriver.ChromeOptions()
options.add_argument(r"user-data-dir=C:\Users\usr\AppData\Local\Google\Chrome\User Data")
options.add_argument(r'--profile-directory=Profile 1')
driver = webdriver.Chrome(service = service, options = options)

Additionally, for MacOS, the executable is stored without the .exe so you must omit it.

Answer 6

"driver = webdriver.Chrome()" is a more modern method, so

simply replace:

driver=webdriver.Chrome(service=ChromeService(ChromeDriverManager().install()))

with:

driver = webdriver.Chrome()
