I am trying to figure out what they did with their older versions and how you can install the old version on Windows 8..
Here are the sources to the old OpenNI version
https://github.com/OpenNI
Here is the driver by avin:
https://github.com/avin2/SensorKinect
some more driver versions:

In this may 2012 forum post, avin adds this note: This version must be used with OpenNI 1.5.4.0! It will not work or compile with previous versions so please be sure to install it.
I'm also going to add support for Kinect4Windows as soon as I get my
hands on one (which will finally happen next week).
Finally I found this download that contains:
openni-win64-1.5.4.0-dev nite-win64-1.5.2.21-dev sensor-win64-5.1.2.1-redist SensorKinect092-Bin-Win64-v5.1.2.1
maybe this works
