How to install Active Directory Client on Windows 8.1 Pro

Hello,

I like to install the Active Directory client on Widows 8.1 Pro.  I have tried installing RSAT (Remote Server Admin Tools for Windows 8.1, but when I run the setup program it says the Windows Update Standalone Installer, the update is not applicable to your computer.  I am running this Windows8.1-KB2693643-x86.msu and downloaded it from here.

So, how do I get this installed?

Thanks

Paul
