I'm on Windows7 64-bit... I've tried everything. Obviously there's no windows 7 drivers for this, so I tried to get the vista ones from the official website. The installer wouldn't even run, until I ran it through vista compatibility. They installed, but it didn't even react to when I plugged the camera in or not. So I tried finding other 64-bit drivers I could find on the net for the quickcam. They would install, and I would manually assign the drivers that match the camera, but then applications say that the 'webcam is in use' even though nothing was using it, obviously... so apparently, it does not work. This webcam is a bit old, but I don't have the cash to buy a brand new one for pretty much.. one person.. so I don't know what to do.
