Ok, I got it working. Hope that helps you: 1) Run Nexus Mod Manager (NMM) as administator. 2) Press cog in the top menu (between "open folder" and lightbulb). 3) Check all three top checkboxes (assotiations). 4) Important: Exit NMM and restart it (as usual, not as admin).
Now you can install this mod. If that doesn't help, try downloading the latest beta version of NMM here: https://github.com/Nexus-Mods/Nexus-Mod-Manager/releases
