Unable to install IE 11, error code 9C59

[Zaptecc]

So my grandma's computer is a pain. She called me over to help her fix it, and guess what the problem was? WINDOWS 10! Thanks Microsoft! Anyways, I reverted it back to 7 because I didn't feel like teaching her how to use a new operating system. Once I reverted it, I noticed that the Internet Explorer icon was missing. On top of that, multiple websites wouldn't display everything properly. I wanted to reinstall IE, so naturally I uninstalled it. And so the latest browser was then IE 10. Great. I tried to reinstall IE 11 and got this error. Not great. I went around looking at articles on this error, and it said to uninstall all the way back to IE 8, so that's what I did. Now I'm at IE 8, and I still get the same error. As far as I know, everything should be compatible, but the update is just being annoying. I tried installing it through Windows Update, I tried the installer from Microsoft, and I tried the offline installer. They all give me the same error. I tried almost everything I know that will work so far. I'm desperate. Please offer insight.

 

It's Windows 7 SP1 if you were wondering.

 

And yes, I know Chrome exists, but I want to fix this now that I've spent so much time on it

Lol, I know, I know, but it's what my grandma is familiar with and I really don't feel like teaching her how to use a new browser.

They're all still basically the same layout (Ex. top search bar, back and refresh buttons, etc.)

Must have IE9 hidden somewhere in the update list. uninstall that too. IE8 is part of Win7 so it has to be removed through add/remove features.

I checked in Windows Update for any versions of Internet Explorer and programs and features lists IE8, so I don't think so.

just get a IE or Edge or Chrome or Firefox installer on a USB stick and install it from there  should work, atleast with chrome
