Update. I moved steam vr to my c drive and driver4vr finally installed the driver and started working. Now I have riftcat and driver4vr listed in the device list. I’m able to specify head tracking via kinect and I can calibrate and use the settings button to get the purple screen. This shows me as a skeleton.
At the top of the screen it says driver4vr isn’t started yet. I click start and it runs for about 1 second and then stops.
I think I read elsewhere on the forum that it might think it’s out of time on the trial? I’m yet to get it running so that seems unlikely?
