I just saw your e-mail for this Posting the response here for anyone else who ran into the same problem:
It looks like your Vive and main monitor may be plugged into different graphics cards. For FlyInside to work, you'll need both Vive and monitor plugged into your NVIDIA 960M.
Just a word of warning, your 960M is a good bit below recommended specs, you may not have the best experience once you get FlyInside running.
