I will try and help you but unfortunately 'will not work on my laptop' could mean lots of different things from installation problems to viewing problems so I will cover both for you.
Firstly I am going to go over installation in case your problem is installation then I'll move on to video capture which is how you will see the images that your webcam captures..INSTALLATION
To install your camera, if Windows 7 does not recognize the camera then you will need to find an appropriate driver. To do this you could try these steps.
1. With the Webcam plugged in, try and do a manual Windows Update. By doing this windows may find the driver for your camera and install it for you.
2. If Windows update didn't find the driver then the following link will take you to a website that I think has the driver you need. Notice it also has a pdf you can download so you can get the original instruction manual.

To see anything from your webcam you are going to need an application that captures video images. As you have Windows 7 and if you haven't done already, you can download Windows Live Essentials. Included in this package is Messenger and Windows Movie Maker. Messenger enables you to use your Webcam for Video Chat and Windows Movie Maker has a Webcam Capture button so that you can make a movie using your webcam.
To get Windows Live Essentials just follow the link below.http://explore.live.com/windows-live-essentials?os=other
I hope this has been of help for you.
