So I wanted to use my old XBox 360 Kinect as a WebCam for conference calls using either Skype or Microsoft Teams. Lots online about how this is possible but most posts didn't work as so old. Here is how I managed to get it working.

This forum had all the details (1st Post):

However I noticed you cannot use the latest SDK v2 to register the KinectCam.ax. You needed V1:

KinectSDK-v1.0-beta2-x64.msi

Once you install this version (uninstall all other versions first) you can then register the KinectCam.ax and the camera is now accessible in Skype. 

However Microsoft Teams would still not see the camera. So for this I installed ManyCam and which used the Kinect Cam and was now usable in MS Teams and all other apps.

You can also adjust the angle of the camera using the file located at (hidden folder) config.ini:

C:\Users\[your username]\appdata\Local\KinectCam

Just change the [CameraElevationAngle]

e.g. I have it at CameraElevationAngle=9
