Hi @ysato, sorry to hear about your issues.
Were you able to at least successfully run the samples included with the Core SDK available @https://github.com/Tobii/CoreSDK
I was able to run both 32 and 64bit variants of these samples on my system without issue
using the Tobii Interaction Nuget Package.
What happens when you try it with for example the Interactions 101 sample?
I did have issues with Visual Studio 2017, and so use 2015.. maybe you can try that?
