Cannot make use of LifeCam Studio in Desktop under Windows 10 ?

Not sure its a app problem or LifeCam Studio issue.
I've purchased a new desktop and install Windows 10 Home edition (fresh install). After using for 1 month, I get a webcam (LifeCam Studio). The cam is good and no need to install anything, the "Camera App" work right away. However, when I launch theTranslator app, when I click on the camera icon, the following message display:
"We couldn't get your camera started. Try using the keyboard to translate."
Check and confirmed that under:setting->Privacy->Camra is turned on and allow translator to use the camera
Why can't the translator app make use the cam and how to resolve it ? Thanks.

I know what happen now. Since I use the camera inside VMWare Workstation 12 i.e. I install Win 10 inside VMWare Workstation 12 and connect the lifecam studio to the guest Win 10.
When I connect the cam to host Win 10, everything work fine. My question now is:
why the camera app in the guest Win 10 work properly but the translator app not ? I understand if both app not able to use the camera, but why camera app work fine in guest Win 10 but translator app not ? Thanks.
