Can't use Unity Analytics in 5.1.1f1

If I add “usingUnityEngine.Cloud.Analytics;” to one of my scripts, then I get this error:

error CS0234: The type or namespace name Analytics' does not exist in the namespace UnityEngine.Cloud’. Are you missing an assembly reference?

I’m using Unity 5.1.1f1 Pro

I tried reinstalling Unity, but didn’t help. Any ideas?

I found the issue. On another thread someone mentioned that if the “Disable HW statistics” box is checked, then the project will not integrate.

in 5.1.1 it’s:

using UnityEngine.Analytics;
