   Driver and sensor issues


I think I'm having driver issues. What should I do?


If you think you are having driver issues, try the following:

  • Make sure there are no Windows security settings or anti-virus software settings that could prevent KScan3D from installing or functioning properly.
  • Sometimes Windows will recognize the sensor—or re-recognize the sensor, in cases where the sensor was previously working—if you unplug the USB cable and then plug it back in.
  • Other USB devices may affect the sensor's performance or ability to work. If this is the case, you may need to switch USB ports, disconnect other devices, or add an additional USB port to your computer.
  • If using a Kinect for Xbox 360, make sure you are using the USB / wall outlet adapter. Some Kinect for Xbox 360 sensors do not ship with this adapter, so it must be purchased separately.
  • If you are using a Kinect, be sure the adapter is plugged into a wall outlet.
  • If multiple sensors are connected to your computer and one or more of the sensors is not working properly, you will not be able to scan. Either fix the sensor connection issues or disconnect the sensors that are not working.
  • If you are unable to scan and you have modified any of the advanced settings, you may need to click the Restore Defaults button on the Settings tab to reset all settings before you can perform a scan. You may also need to close KScan3D, delete the folders in My Documents > KScan3D > Calibrations, and restart KScan3D.
  • If KScan3D displays sensor-related errors such as "Scanner1 is not connected" or "Could not connect to OpenNI scanner", these are usually caused by driver-related issues. Try using the Device Switcher application to unload other installed drivers and load the KScan3D drivers. Rebooting your computer after switching drivers may help.
  • If KScan3D fails to launch or run properly and you have no need for other sensor-based drivers that may be present on your computer, you may want to do a full uninstall and reinstall. Follow these steps:
    1. Uninstall KScan3D.
    2. Go to Control Panel > Uninstall Programs and uninstall every sensor-based driver listed (PrimeSense, OpenNI, Kinect for Windows/NUI, or libfreenect).
    3. Reboot your computer.
      This is an important step, as it should clear previously installed drivers from your computer's memory.
    4. Reinstall KScan3D.
      Make sure you download the latest version from
    5. Reboot your computer again.
    6. Plug in your sensor and wait for the confirmation pop-up to say that your device is ready to be used.
    7. Launch KScan3D.
