Cant turn on RSAT (0x80073701) in Windows 10

rsat-2For about 10 days ago, I tryed to install RSAT (Remote Server Administration Tools) on my work computer.
I downloaded the latest version, WindowsTH-RSAT_WS2016-x64.msu and run the installation. But when I went to turn RSAT on, I got the error message:

The referenced assembly Could not be found.
Error code 0x80073701
Tell me how to solve this problem

Unfortunately, Microsoft’s solution was not the right one for me.

But today (10 days later, and a variety of attempts to activate the RSAT) so I got to it.

I took the downloaded file, WindowsTH-RSAT_WS2016-x64.msu and packed it up (using 7-zip) to C:\RSAT
I started PowerShell as Administrator and went to the path: C:\RSAT and wrote:
DISM /Online /Add-Package /PackagePath:C:\rsat\

After DISM (Deployment Image Servicing and Management tool) run through, I also execute .\ Rsatcustominstaller.exe in the PowerShell window.

A restart later, and RSAT is in action.
