Arsenic on Windows ################## .. _ie11: Internet Explorer 11 ******************** If you're trying to run Internet Explorer 11 using IEDriverServer, you must configure your computer a certain way.

On Windows, you need to explicitly pass the absolute path to the services binary to the service. For example, if you installed ``geckodriver.exe`` to ``C:\geckodriver\geckodriver.exe``, you have to instantiate your arsenic session like this:: from arsenic import get_session, services, browsers async def example(): service = services.Geckodriver( binary='C:\\geckodriver\\geckodriver.exe' ) browser = browsers.Firefox() async with get_session(service, browser) as session: ...
