Is it resolved? Got same issue on unity 2018.2.1f1.
It seems the updated sdk and jdk1.8 did the trick on this version of unity.
Hi, I have same problem, about a couple of weeks it worked, but now shows that error. It happens using unity 5.5.4p4 and 2017.3.1.p3
What can be happening?
Hi, it is the same with me. The installation is correct and the c# samples provided by nuitrack work properly. I just can’t get my unity builds to run using unity 5.5.4 personal edition.
Please make sure that you use 64-bit version of Nuitrack with Unity.
Hello, Olga.
Today I downloaded the nuitrack to test my new pc.
But it didn’t work because of this exception.
So I replaced nuitrack with nuitrack file of old pc.
Then, it didn’t throw exception.
What happened between version 0.22.1 and version 0.23.1?
Hi younger,
Do you encounter this error when running Unity samples?
What is the “nuitrack file” that you replaced?
I do use 64-bit version. Unfortunately I still run into the the same trouble.
There could be the following solution to this problem:
Hi Olga, first of all, thanks for the help. I already have set the import settings in that way.
Still getting the exception in the Unity examples and my own builds. I also use x64 version and triple checked the environment variables. They all echo correctly. C# examples also work out with my Orbec Astra and RealSense D435 (Is that actually a proper test to see if the installation works correctly?).
However, when I reinstalled the sdk lately I encountered an error in the CamRotation script “GameVersion does not exist in the context”. I had to comment those sections out in order to get started. What does GameVersion do and could it be a reason for my missing DLL issues?
Is there a way to manually copy the nuitrack LIB in the build folder of the Unity project?
Hello Olga,
I’m sorry I didn’t write well.
I downloaded version 0.23.1 at nuitrack.com and played it but didn’t work.
So I changed version to 0.22.1 then it didn’t throw exception.
I think 0.23.1 has this problem and this post uploaded after version update.
Thank you.
Hi Letgo,
We’ve reproduced your issue.
When importing NuitrackSDK.unitypackage to your Unity project, you have to tick all the components (folders, scripts…) shown in the window “Import Unity Package”. They’re all ticked by default. It seems that you unticked some folder or script.
4 months later and still no satisfactory answer. Can anyone tell me where to simply get ‘libnuitrack’ DLL file so I can manually install?
I found it in nuitrack-win64\nuitrack\bin

Hi Olga,
I am having a similar issue. I am trying to see if Nuitrack will work with my companies software to replace the Kinect, but this issue is blocking any progress. I have the nuitrack_c11_sample working fine, I just cannot get the C# example solution nor the Unity example to work. I’ve tried reinstalling everything, checking my environment variables, and checking my versions. My visual studio solution won’t let me manually add the missing references to the solution. I had it working at one point a couple weeks ago but now it doesn’t. Is there any solution you can think of? Maybe I could try using an older version of Nuitrack?
Anybody find any solution regarding dll not found exception?
Ive also imported the dlls from the installation folder to unity but still having same issue
Hi, I did some investigation on importing DLLs in unity. I found some issues that had to do with the fact that unity could not support .net- framework 4.5. It should be solved with the more up-to-date releases.
So check if you can select the higher framework in the player settings of unity. Also make sure that you have switched your architecture to x86_64 as the default is only x86. At least this did the trick for me.
Hi all,
I encountered similar issue previously, please refer to this post Can't find out how to properly setup Nuitrack it helps to solve my issue
I managed to run the unity tutorial properly after setting up the environment in C:\nuitrack and class path in C:\nuitrack\bin as well as locate the nuitrackSDK in C:\nuitrackSDK
Hope it helps
Hey All, had the Same problem, Unity Throwing:
DllNotFoundException: libnuitrack
when I was trying to run “NuitrackSDK > Tutorials > First Project > BasicSkeleton.unity” scene with Intel RealSense D415 on Windows 10.
Fixed by:
- Updating camera firmware
- Installing latest version of Unity (2018.2.15f1)
- Installing Nuitrack (under C:\nuitrack) by following the instructions here
- Making sure both of the environment variables (“Path” & “NUITRACK_HOME”) are defined correctly as described in WINDOWS > Step 4. on the instructions webpage above.
