Unable to find element on closed window in Python using Selenium

Question

def check_text(browser, sitename):

    browser.get(sitename)

    try:
        text = browser.find_element_by_class_name("text_content").text

        if "foo" in text:
            print("ok")

        else:
            print("not ok")

    except NoSuchElementException:
        print("no such elem")


def check_internet_explorer():

    sitename="*foo site*"
    caps = DesiredCapabilities.INTERNETEXPLORER
    caps['ignoreProtectedModeSettings'] = True
    ie = webdriver.Ie(capabilities=caps)
    check_text(ie, sitename)

This code works just fine on windows 10. When I try to run it on windows 7, the webpage loads but I get this error: "Unable to find element on closed window" I looked for this error online and it's something about internet explorer protected mode. I tried adding the "ignore protect mode settings" capability, but I get the same error. What can I do?

Here is the Answer to your Question:

When you work with Selenium 3.4.0, IEDriverServer 3.4.0 with IE(v 10/11) the error: "Unable to find element on closed window" may occur due to several limitations of Internet Explorer and the IEDriverServer.exe. To prevent those errors we can explicitly set the nativeEvents and requireWindowFocus to true through the DesiredCapabilities class as follows:

caps = DesiredCapabilities.INTERNETEXPLORER
caps['ignoreProtectedModeSettings'] = True
caps['nativeEvents'] = True
caps['ignoreZoomSetting'] = True
caps['requireWindowFocus'] = True
caps['InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS'] = True
ie = webdriver.Ie(capabilities=caps)

As you are facing issue on Windows 7 the documentation mentions the following points: On IE 7 or higher on Windows Vista or Windows 7, you must set the Protected Mode settings for each zone to be the same value. The value can be on or off, as long as it is the same for every zone. To set the Protected Mode settings, choose "Internet Options..." from the Tools menu, and click on the Security tab. For each zone, there will be a check box at the bottom of the tab labeled "Enable Protected Mode".

You can find more documentation about these facts in this link.

Unfortunately, the exact same error appears, after I tried what you said. – cosminp Jul 26 '17 at 08:20
Is your `Zoom Level` set to 100% ? Selenium, IEDriverServer & IE version please. Thanks – undetected Selenium Jul 26 '17 at 08:22
Yes, zoom level is set to 100%. IE version: 11.0.9600.17843 (IE 11). Selenium version: 3.4.3. IE webdriver version: 3.4.0.0 – cosminp Jul 26 '17 at 08:24
@cosminp Did you get a chance to cross check the settings mentioned in the link I provided in my Answer? Thanks – undetected Selenium Jul 26 '17 at 08:56
I tried every possible arangement between those 5 settings (including the last one, with flakiness) and it's still the same result. – cosminp Jul 26 '17 at 09:13
Can you please confirm the Protected Mode settings once? Thanks – undetected Selenium Jul 26 '17 at 09:15
I confrimed the Protected Mode settings and the same error appeared. After that, I confirmed the intranet settings and I get the same error. – cosminp Jul 26 '17 at 09:23
Can you switchover to `32-bit IEDriverServer.exe` even if your IE (11) remains 64-bit? Update me the status please. Thanks – undetected Selenium Jul 26 '17 at 09:28
Can you share the URL if it is a public one? Thanks – undetected Selenium Jul 26 '17 at 09:31
In my path (C:\Python36\selenium\webdrivers), I replaced the 64 bit IE webdriver with the 32 bit one. The error is still there, unfortunately. – cosminp Jul 26 '17 at 09:33
