Webcam working!
First: Thanks for your replies here on this forum.
My post at Sony support forum:
"After many hours of un-installing, installing, searching forums for answers, etc, I finally fixed this problem myself. The Imaging Device (Sony Visual Camera or Motion Eye) was not present in the Device Manager. I simply could not get the driver to appear. Finally after 12 hrs of working on this in desperation, I decided to unplug the USB camera in the top of my laptop lid. It is a very tiny connector, but I got it disconnected. I then re-started. Shut down and then plugged it back in. THE DRIVERS THEN INSTALLED! HALLELUJAH!"
Bottom line, I tried to follow Sony's own recommended driver install order (ugrade from Vista to Windows7) but it would not work. Some of their drivers would not install. Someone here posted that the Intel Graphics driver needed to be installed first. I believe that may have been the problem because I remember I couldn't get it to install until later. Thanks for the help.
