I have the QX3 and had to get the software and drivers from Digital
Blue, once loaded up it did fine. Of Course I couldn't get it to work
on my new Vista Computer but there might be a light at the end of the
tunnel.

I understand that the Mac version of the software not only runs the
QX3 and QX5 but also many other brands of cameras and webcams as
well. One of the mac versions called macam from Source Forge list a
full page of cameras it works on.

I know the mac software don't work on a Windows pc but I'm wondering
if anyone knows any other microscope or webcam software that will run
the QX3 in windows vista.

Digital Blue does not provide downloads that work in cista and
neither does Intel.
