Windows Update Readiness Tool Literally "Fails" to install

[Lemonaxe]

To be honest, I just downloaded Windows Update Readiness Tool because my "Turn Windows Feature On or Off" shows up blank every time I open it just like the picture attached.

So, I researched that the way to fix it is by installing Windows Update Readiness Tool, and so, I did. But, when I try to install, it LITERALLY "fails" to do so (as seen on the other pic) . Can anyone help me resolve this problem? I want a concrete answer with steps for me to follow. I don't care however complicated those steps may be, as long as they definitely fix the issue.

Thanks to all who help
