To prepare for reinstalling Internet Explorer 11, I followed these steps to remove possible corrupted previous Internet Explorer update:
"Removing IE 11 in Windows 7 is simple, but the option is a little hidden away. You’ll need to crack open the Control Panel -> Programs -> Uninstall a program.
From here, you’ll need to click View installed updates on the sidebar. Then find Internet Explorer 11 in the list view, right-click on it and hit Uninstall"
Then I used the IE11 installation link suggested by JA.
Everything seemed to be going fine till I got this message: "Internet Explorer did not finish installing" --- along with a link to "Internet Explorer Troubleshooter"
There was nothing in that link that seemed to apply in any way to my circumstances.
