As I mentioned in another thread ( Enable Mixed Reality Remoting ), I think it might be because a Unity DLL has not been packaged with the app. The DLL PerceptionRemotingPlugin.dll seems to be included in the Unity install but that doesn’t help when you are trying to deploy to other machines. I haven’t tried copying that DLL on to my test machine, maybe that would work. I was just hoping that there would be another patch and it would fix my issue
