PdhAddCounterW() failed: unknown error when starting a demo - openvino

Question

I followed instructions on https://docs.openvino.ai/latest/omz_demos.html#doxid-omz-demos.
I finished the setup/installation, downloaded the needed models with the omz_download tool and tried to start the interactive demo:
interactive_face_detection_demo ^ --loop ^ -m "C:\Intel\face-detection-adas-0001\FP16\face-detection-adas-0001.xml"

[ ERROR ] PdhAddCounterW() failed: unknown error
How can I get more information about that error / is this a problem with my setup?
(I was able to get everything running on another machine)

Answer 1

Your error appears to be related to Windows performance-counter-API and this error is not related to OpenVINO. For more information about PdhAddCounterW(), you can refer to PdhAddCounterW function (pdh.h).
On another note, try specifying input to the demo as it requires an input to process. Here is an example command:
interactive_face_detection_demo -m "C:\Intel\face-detection-adas-0001\FP16\face-detection-adas-0001.xml" -i <path_to_video>\<input_video>.mp4
