LicenseNotAcquiredException occured by trail License

I use trail license to test skeleton tracking in windows 10(64 bit) / VS2015 C++.

I have gotten trial license from activation, and test Nuitrack middleware by [~nuitrack\activation_tool\Nuitrack.exe] .

But when I run my demo, the LicenseNotAcquiredException occured in the calling
The trail license cannot used in Nuitrack SDK?

BTW: When I run [~nuitrack\activation_tool\Nuitrack.exe] , Must run it by administrator,
Or it will not display the depth image. Is there any solution for it?

Do you see the depth map after you click “Compatibility Test”?
If yes, please go to %NUITRACK_HOME%/data. Do you see the file “e24b…”?
If the file is created, please close the activation tool and run it again.
If this file wasn’t created, please run the activation tool as Administrator.
If you don’t see the depth map after you click “Compatibility Test”, please run “nuitrack_sample” from %NUITRACK_HOME%/bin and provide us with the console output.

  1. I see the depth map after click “Compatibility Test”
    I have input the trail license, and can run the sample for 3 minutes trail.
  2. There is no “e24b…” file in the folder %NUITRACK_HOME%/data
  3. I have run the activation tool as Administrator, and confirmed it on 3 PC
  1. I can see the depth map, and run for 3 minutes after inputing the trail license.
  1. There isnot “e24b…” file in the folder %NUITRACK_HOME%/data
    I have confirm in 3 PC, and got the same result.

The trial version has a limit of 3 minutes. After the activation of a license, the “e24b…” file turns into “license.json” that is located in your “data” folder. Please advise are there any unsolved issues?
