Hello,
I am trying to run nuitrack_csharp_example for the first time. I am using the RealSense D435 camera with Windows 10, Visual Studio 2017 x64. I have activated my Nuitrack license, followed the README file and this thread to complete my setup thus far.
The project builds in Visual Studio and I copied the nuitrack_csharp_example .exe to the parent folder as seen in the following screenshots:
When I run the nuitrack_csharp_example.exe from the nuitrack_csharp_example folder with my Intel camera plugged in and ready to go, this is the exception I am receiving:
SETUP - COM already setup - threaded VI might not be possible
Create DepthProvider: Realsense2DepthProvider
Unhandled Exception: System.Runtime.InteropServices.SEHException: External component has thrown an exception.
at nuitrack.NativeImporter.nuitrack_CreateUserTracker(IntPtr& ptr)
at nuitrack.NativeUserTracker..ctor()
at nuitrack.UserTracker.Create()
at nuitrack.MainForm..ctor()
at nuitrack.Program.Main()
The program exits shortly after that.
I hope you will be able to help me with this issue, and I am happy to provide any further information required.
Could you provide the information about architecture [x32/x64] of your:
– Windows OS;
– Nuitrack;
– CMake Generator;
– build configuration for nuitrack_csharp_sample?
We noticed that you use different architectures for CMake generator and for build configuration in Visual Studio:
– in CMake, you use a x32 bit generator (Visual Studio 15 2017);
– in Visual Studio, you build project with Debug x64 configuration.
Hi Iosif,
Thanks for getting back to me. I am using a 64bit Windows 10 machine, with a Nuitrack x64 installation. I deleted my build directory for nuitrack_csharp_example, deleted the cache in CMake, configured and generated again using the Visual Studio 2017 x64 compiler as in the screenshot:
This is the output in CMake for the configuration above:

Configuring done
I generated and built the project in Visual Studio 2017 using the x64 compiler. The build completed successfully.
I copied the .exe to the nuitrack_csharp_example. I executed the program and got the same exception as above unfortunately.
I believe I am aligned to 64bit entirely throughout my build. Is there anything else I should be checking? I would certainly be interested in purchasing the Nuitrack Pro Perpetual package should I get the trial version working to my needs.
Thanks again,
Emma
Could you try switching CMake to Advanced mode and changing CSHARP_PLATFORM from “anycpu” to “x64”?
If this does not help, then you need to provide the entire list of CMake parameters and try to build other samples, for example, nuitrack_console_sample or nuitrack_gl_sample
.
