Most Internet Explorer 11 installations are straightforward and work the way they should. But it's possible that you might have problems.
If you do, you can:
Check that you meet the minimum operating system requirements and have the prerequisites installed.
Check that there are no other updates or restarts waiting.
Temporarily turn off your antispyware and antivirus software.

Make sure you use the same download server URLs that you entered during the Setup process.
Internet Explorer didn't finish installing
If Internet Explorer doesn't finish installing, it might mean that Windows Update wasn't able to install an associated update, that you have a previous, unsupported version of IE installed, or that there's a problem with your copy of IE. We recommend you try this:
To fix this issue
In the Control Panel, open the Programs and Features box, scroll down to IE11, and then click Uninstall.
After the uninstall finishes, restart your computer.
Run Windows Update, clicking Check for updates.
Check the list for IE11. If it's included in the list of updates for download, exclude it before you update your computer.
If you get an error during the Windows Update process, see Fix the problem with Microsoft Windows Update that is not working.
Restart your computer, making sure all of your the updates are finished.
Try to reinstall IE11 from either Windows Update (if you saw it in Step 3) or from the Download Internet Explorer 11 website.
