Using a Kinect sensor with a PC is still considered an experimental technology.  While it has proven to perform consistently once connected, it has been known to start up inconsistently if it is connected out of sequence.  This machine already has Kinect sensor drivers properly installed, so there will never be a need to update them.  We’ve had the best luck getting the Kinect sensor to run consistently by following this sequence:

1. Turn on the computer.
2. Let all stages of start up finish completely (wait until tray icons stop appearing)
3. Assuming the Kinect sensor is already connected to the USB/power adapter, plug the USB cable into the computer.
4. Wait a few seconds.
5. Plug in the Kinect sensor’s power to an outlet.
6. Wait until the machine recognizes the sensor before opening any software which uses it.  It will not always make it clear that it has recognized it, so just waiting about ten seconds will do the trick.

2. Application starts, but does not detect users

5. Check that the sensor is powered and plugged into the computer.
6. Make sure nothing is obstructing the view of the Kinect sensor.
7. If the depth sensor is not working while the rest of the unit is

1. Restart the computer.
2. Test the sensor again.
3. If it still does not work

1. Power down the machine.
2. Unplug the Kinect sensor from the machine and its power.
3. Power the machine back up and let it complete all startup processes.
4. Connect the sensor to the machine.
5. Wait a few seconds.
6. Connect the sensor’s power.
7. Wait a few seconds.
8. Run the test again.
9. Run the application when ready.

I saw a thread a possible solution for the error of Cinder-block xcopy KinectSdk, I saw that is a matter ofupdating the sdk dir but not working properly, change the path before me said she could not include "NuiApi.h"to modify the path and decision to run the program but throws me errors mInput

error C2065: 'mInput': undeclared identifier
Error C3861: 'create': identifier not found.

1. Add this line to your implementation:
   using namespace KinectSdk;
2. Prefix your Kinect objects with the namespace:
   KinectSdk::KinectRef mInput;
   ...
   mInput = KinectSdk::Kinect::create(); 

1. gl::pushMatrices();
2. gl::translate( 1.0f, 1.0f, 0.0f );
3. gl::draw( mTexture );
4. params::InterfaceGl::draw(); // <-- error
