Logitech webcam So I bought a logitech webcam online at ebay. Let's say it's not working. I spent 16 dollars on it. It just came with the camera and no installation/instruction manual at all. And now, after I tried just downloading the webcam into my computer, it gives me an error message saying that this product isn't meant for my operation system. I have an acer. What operating system is this? I'm very mad because I spent 16 dollars on this webcam. And now it won't work on my computer.
