Cannot install IE11 on Windows Embedded Standard 7

I have downloaded the 'full' installer for IE11 (IE11-Windows6.1-x64-en-us.exe).

The page here lists prerequisties that are required to install IE11: https://support.microsoft.com/en-ca/kb/2847882

I have installed all of the updates on this page that are applicable to WES7. When I run the installer, it tries to do some stuff, then comes up saying

Internet Explorer needs an update before installing. Go online and install the required update, then return to the Internet Explorer installation page and run setup again.

When I click the Get Update button, surprise surprise, it directs me to the previous page I linked! The one with the list of updates I've already installed!

How can I install IE11 on WES7?

Edit:

Even in IE11_main.log file, it says it is trying to download 3 update packages that are already installed.

The actual log details:
