Hi! Please provide us with the information about your environment:

  1. Nuitrack version
  2. Nuitrack SDK version
  3. Sample you’re running
  4. Sensor model

Also, if it is a Unity sample, then you need to check Architecture in Build Settings (Ctrl + Shift + B): change x86 to x86_64, if necessary
