UnityKinectDepthExplorer - how can I use this example with Kinect v1? - unity3d

Question

I'm interested in displaying Depth data in Unity with Kinect for Windows. Unfortunately, I have Kinect v1.8 and I know this has been easily done with Kinect V2 (Kinect Fusion).
I found this example: https://github.com/rickbarraza/UnityKinectDepthExplorer
I installed all the necessary components and now getting DLLNOTFOUNDEXCEPTION:
Failed to load 'Assets/Plugins/x86_64/KinectUnityAddin.dll'
Concerning all the posts and forums I've been reading so far, It's because I'm using SDK 1.8 (instead of SDK 2.0).
Is there any way how I can use this example with Kinect v1.8? I tried to contact the author as well but he haven't responded back.
Thanks a lot!

I had the same Problem in an University Project maby its not to late for you.
This is an Kinect v1.8 Wrapper i made to read the kinect depth image only. I used the Kinect with MS-SDK from the Unity-Assetstore as an orientation, you dont have to download it. All you need is this Code.
Use The Init() Method to start and the GetDepthArray() Function to get the Deapth Frame.
hope it works for you !
You have to install the Kinect 1.8 sdk or have at least the Kinect10.dll from the 1.8 sdk in your Windows/System32 folder
