I just got a Microsoft LifeCam cinema, which was advertised as being Windows 7 compatible. I loaded the software before plugging in the instructions. But while this works on my Windows Vista laptop, and my home desktop Win_XP not work with my Win-7 64-bit desktop, which I bought the camera. When you run Microsoft LifeCam 3.0, which says there is no camera connected to this computer. Just after turning off the camera and plug it back, even after restarting the computer, even after uninstalling and reinstalling win_7 downloaded LifeCam 3.0 32 and 64-bit, Microsoft's Web site.
