Can't Use Webcam Inspiron 5737

I reinstalled Windows 7. Now I can't use my webcam. It recognized my webcam as 'integrated webcam' you can see it in device manager under imaging devices and it says it is working fine and the value is USB video device. My problem is I do not have Dell Webcam Central so I can not open the webcam. I didn't get reinstall discs when I bought my laptop. Also if I go to my dell downloads it only shows Mcafee and Cyberlink Mediasuite. How can I reinstall Dell Webcam Central?
