Can not find user in unity build

I’m following the Creating your First Unity Project using Nuitrack SDK. I’m stuck at finding the user since the camera doesn’t seem to get activated when I run the build. I’ve tried the samples with a trial license and they work. Not sure how I should connect the camera with unity builds. Please help.

Dear ryanfjh.

Try running Unity as an administrator.
Also update the Nuitrack SDK and Nuitrack Runtime to the latest version.

Can you provide the Console output in Unity?

Looking forward to your response.
