Question

Code block:

import time
from selenium import webdriver

browser = webdriver.Chrome('C:/Users/Cypher/Downloads/chromedriver_win32.zip')
browser.maximize_window()
browser.get('https://www.google.com/gmail/')
email_field = browser.find_element_by_id('identifierId')
email_field.clear()
email_field.send_keys('My mail')
email_next_button = browser.find_element_by_id('identifierNext')
email_next_button.click()
time.sleep(1)
password_field = browser.find_element_by_name('password')
password_field.clear()
password_field.send_keys('My password')
password_next_button = browser.find_element_by_id('passwordNext')
password_next_button.click()
time.sleep(100)
browser.quit()

Error:

OSError: [WinError 193] %1 is not a valid Win32 application

Answer 1

Just extract the chromedriver you have downloaded... chromedriver_win32.zip make sure you have the chromedriver.exe file in the downloads...

browser = webdriver.Chrome('C:/Users/Cypher/Downloads/chromedriver.exe')

Hope this helps you!

Answer 2

This error message...

OSError: [WinError 193] %1 is not a valid Win32 application

...implies that the argument which you have passed to initialize Chrome was not in the valid format.

You need to consider a couple of facts as follows:

• When you simply pass the absolute location of the ChromeDriver by default it is considered as the Value for the argument executable_path which accepts a value of an executable binary
• As you are on Windows OS you need to extract the chromedriver.exe from chromedriver_win32.zip and place it anywhere within your system.
• Next you need to pass the absolute location of the chromedriver.exe along with the argument executable_path .

• The argument executable_path must be supported with a Value as either of the following:

  • r'C:\\path\\to\\chromedriver.exe'
  • "C:/python/chromedriver.exe"
  • "C:\\\\python\\\\chromedriver.exe"

• The working line of code will be:

   from selenium import webdriver browser = webdriver.Chrome(executable_path=r'C:\\path\\to\\chromedriver.exe')
