I recently purchased a used Latitude E6540 and in setting it up for Skype the webcam doesn't show up. In the original configuration it shows 839RM Creative Camera Module kit was installed. And at the top of the lid is the eye for the camera. When I access Device Manager imaging devices are not displayed. This computer was upgraded from the original Windows 7 to Windows 10. And TLS 1.1 and TLS 1.2 are clicked on. Does anyone have any suggestions to get this webcam working as the warranty has expired.  Thank you as any help will be greatly appreciated.
