Dell N5110 Dell Webcam Central is working fine,But in case of Webcam Center/Manager I get message saying "No supported webcam driver detected.Please install the webcam driver using the Dell Resource CD and launch Webcam Center again."

I have a problem with my dell laptop 64bit.Windows 7 OS.while i can take photos from Webcam central not so with webcam Center as it requests to download drivers.The webcam is not to be seen in device and printers section,but under imaging devices I can see Integrated webcam,How to resolve this issue so that I can use the Dell webcam center please advice.Thanks
