Kinect color source: Access violation

Hi,
I am using a Kinect and the Image Acquisition Toolbox (R2013b) to capture color/ir and depth data from the Kincet via Matlab. Everything (capturing, preview,...) works fine, but if I use GETSELECTEDSOURCE() to read out the device properties, Matlab crashes every time and shows an access violation.
However, this happens ONLY for the color source, i.e. for the depth camera GETSELECTEDSOURCE works fine! Does anyone face the same problem or has any hints for me?
Greets, Thomas

Hi all,
Can you launch Kinect Explorer and let us know if you can actually see any of the color sensor properties in the kinect explorer Tab?
Thanks

Are you using Windows 8 with Kinect for Windows sensor? Thanks, Madhura

I think you used Kinect V1 for Xbox instead of Kinect V1 for windows. I encountered the same problem with the xbox version, yet everything works fine with the windows version.

Hi, I also encountered this error when I launched kinect to preview the color sensor in the image acquisition toolbox(2014a).Depth sensor seems to work fine.

I have a similar problem but matlab 2015 does not work with color/ir and depth data. Can you solve the problem? Thank you

I was getting the same error with Matlab 2015a on kinect for xbox. I implemented the following code and got the desired output without any errors:
vid = videoinput('kinect', 1, 'RGB_640x480');
triggerconfig(vid,'manual');
set(vid,'FramesPerTrigger',1);
set(vid,'TriggerRepeat', Inf);
set(vid,'ReturnedColorSpace','rgb');
start(vid);
trigger(vid);
colorImage= getdata(vid);
stop(vid);
