The provided link doesn't appear to have anything to do with updating the web cam on a computer. There is information about internal board parts, but the information doesn't point to an update and is over the heads of most end-users. It may be the manufacturer of the web cam, but an update to be used by a run-of-the-mill end-user is impossible to locate.
Unfortunately, the program can't be downloaded as it has been discontinued by the developer.
