OSError: [WinError 193] %1 is not a valid Win32 application error using GeckoDriver and Firefox through Selenium and Python on Windows

I created script with selenium in Ubuntu and works just fine there, but when I moved it to windows10, I get lots of error and I tried to fix it one by one until I see this error. I've been looking for the solution to this problem but I am unable to resolve this error.

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

This is happen when I tried to open webdriver using selenium.

self.myday_driver = webdriver.Firefox(executable_path=self.PATH)

and is there any method to move script from Ubunto to Windows without getting error?

Solution

  • This error message...

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

    ...implies that the underlying OS doesn't recognizes %1 i.e. the system variable PATH as a valid Win32 application i.e. a executable binary.

    To initiate a Selenium driven GeckoDriver controlled Firefox session you need to:

    • Download the latest version of GeckoDriver binary version, place it in your system.

    • Next in your code block you need to mention the absolute path of the binary through the Key executable_path as follows:

      from selenium import webdriver

self.myday_driver = webdriver.Firefox(executable_path=r'C:\path\to\geckodriver.exe')
