Windows 10: Can't install .NET framework 3.5, have been dealing with this for months.

I can't remember everything I've done to try and solve this, but I do know that I get this error code every time I try to install it. Whether its through steam, the command prompt, or the control panel, it just gives me this error. Coincidentally, my computer hasn't been able to properly update since I started having this problem..
