I have got a laptop (as I have said in other threads) but I am having a problem trying to set up the web cam. I cannot find any insrtuctions in my manual, or online to tell me how to do it. What can I do?

When you bought your webcam they must have given you an installation CD along with the Webcam. Try installing the software in the CD first and plug your Webcam after that and it will most probably work. If you didn't have the CD given try searching the company's webcam software downloads by mentioning its versions.
