Vista - Cannot Download and Install Software for Lifecam

I bought a Windows Lifecam VX-5000 webcam. I have Vista Home Premium 32bit operating system. When I put the CD in and attempt to install LifeCam 2.0 software, it tells me "Setup cannot continue because you are not connected to the Internet or the server is unavailable." Whenever I try to download from the MS site, it tells me I have clicked on a "broken link." Can anyone pleaseeeeee help me??

I am looking at that particular hardware sitting on top of my monitor. It
works quite well.
Vista 32 and 64 should recognize and install this hardware without the
installation disc.
If your computer is not recognizing and installing the Lifecam when it is
plugged in there is something wrong with the unit or your computer.
The Microsoft software is useless anyway, no surprise there.
Presumably you are going to use Skype or something of its sort, and that
software will allow you to test the Lifecam, take snapshots or do what you
like.
