Do not know if the drivers for the camera are installed, since I have never used them in almost 10 years.
Your laptop should actually have a "camera" program.
But he didn't. At least I don't know of any.
You can click on the Windows symbol (if it is a Windows laptop) and search for a camera.
Have a look at the Device Manager. The camera should either be listed as a camera with a suitable driver or as an unknown device.
