I am using internet explorer for automating a website process. The website functions only in internet explorer and I can't use any other browser.

Tech used : Python3, Selenium, InternetExplorer

The code works perfectly for chromedriver. However, for InternetExplorer after performing a click on the first page, nothing works and the next steps begin to crash.

I tried debugging for error by pressing F12 to open Developer Console. Surprisingly enough, everything begins to work perfectly well, with a few minor glitches.

Could someone explain me how this can be fixed. Are there some preferences I need to change in order for me to be able to access the functionality without Developer Console.

I was getting the following error : 

NoSuchWindowException: Currently focused window has been closed

Alternately, I tried to perform click by javascript using document.findElementByID().click(), works for certain cases not all.

    Does [this](https://stackoverflow.com/questions/51775122/nosuchwindowexception-no-such-window-window-was-already-closed-while-switchi/51788519#51788519) helps you? – undetected Selenium Jul 11 '19 at 07:00
  • @DebanjanB I have tried the steps mentioned in the post. I am not switching the window though, but yet I tried both WebDriverWait and time.sleep(). The click works for dropdown menu, but not for the buttons even then. – Mayank Jul 11 '19 at 07:32

When you attempt to interact with a selenium element, you get:

Exception in thread "main" org.openqa.selenium.NoSuchWindowException: Currently focused window has been closed.

Make sure you have changed the protected mode (see above: https://github.com/seleniumQuery/seleniumQuery/wiki/seleniumQuery-and-IE-Driver#change-the-protected-mode-in-all-zones).

Also, again, did you execute all steps of the Required Configuration?

In case you are in doubt, the last point:

For IE 11 only, you will need to set a registry entry on the target computer so that the driver can maintain a connection to the instance of Internet Explorer it creates. For 32-bit Windows installations, the key you must examine in the registry editor is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE. For 64-bit Windows installations, the key is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE. Please note that the FEATURE_BFCACHE subkey may or may not be present, and should be created if it is not present. Important: Inside this key, create a DWORD value named iexplore.exe with the value of 0.

Is the same as executing a .reg file with this content (example for the windows 64 bits above):

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE]
"iexplore.exe"=dword:00000000

Reference:

NoSuchWindowException: Currently focused window has been closed.
