Cannot install VX-6000 on my Vista computer

Ok, so, since the CD it came with was version 1.1 I immediately downloaded
the latest driver (v.2) from the Microsoft support site. I proceeded to
install the software, connect the webcam when instructed--and here was when
I encountered issues. At first it would just recognize it as a CAMERA20 (as
in 2.0), and it couldn't locate the drivers. I attempted to have the
computer search for them in tthe Lifecam folder, but to no avail. Next, I
attempted to install version 1.3 of the software and, while it now recognized
it as a VX-6000, it wouldn't install properly, as it stated some portion of
the program stored in the INF folder contained data compatible with Windows
95. It also recognized the webcam again, as a CAMERA20 and, of course, the
drivers were unable to be installed. Now, I installed version 2.0 and this
time it did recognize my hardware as a VX-6000 (as well as a CAMERA20) and it
does not work. When I open the Lifecam application, I receive a "no camera
has been found" error. I know this is all confusing, but could someome
please help??!!
