Hi First unplug it from the computer, Then make sure its turned on / powered on and plug it to the next port. If a autorun message comes up, click run autorun or setup, that should install the Flipshare software, if that does not come up, then open my computer or computer icon which you will find from either your desktop or from the start menu. In my computer you should find the camera, possibly as a removeable storage device, open it, inside you should find a program to install the flipshare software to your machine, Then it will be quite simple to use the camera together with your computer to share videos and so on.
