Crystal Eye Webcam is not listed in my Start menu. My webcam works in MSN, Yahoo, anywhere, but it does not show in the Start menu. So I can't just turn it on and take pictures. It does show in Device Manager though.
Try to install the application again. If you have Windows Vista, 7 or 8, you will need to make use of the Run as Administrator option so that the setup package has access to system's components and privileges. Then you can see it in the Application's menu and Startup (only if you check it).
