Hi,
Thank you for writing to Microsoft Community Forums.
I understand your query related to using AverMedia webcam on your PC, and I certainly appreciate your efforts in trying to resolve the issue.
One of the things that you can try is installing the Assist Central app and try to update the firmware for the webcam and see if you are able to use it. The app can be downloaded from the AverMedia website
However, as you mentioned that you were unable to use the webcam on another PC as well, then you may need to get in touch with the AverMedia support once again and see if they can assist you further.
Regards,
