I Have a Vaio CW Series and How do I operate Camera?

i\’ve a vaio CW notebook and installed windows 7. the camera capture utility has vanished. i have checked the support page for this model but no driver names/applications seem to refer to the camera utility. Could anyone advise me where it is? I Have WebCam Companion but it states im out of trial and i needto pay 40 dollars to have it. So I dont want to do that.
