Hi shankershail15, we need much more information before we can help you!!!
After a quick look on Google, it seems that the Amcap software allows you to record your webcam stream.
From this site : http://amcap.en.softonic.com/
License:Trial versionLanguage:English Developer: Noeld | More programs (8) OS:Win95/98/98SE/Me/2000/NT/XPUpdated:May 3, 2011
It seems that the software only supports upto Windows XP! :-(
Sorry, but unless you can find a windows 7 driver else where, or you have Windows 7 professional, and try to run/install software in XP mode, your stuck!
