If the software doesn't detect the camera, then it means something is wrong with its installation and the best way to check this is from the Device Manager (Start > Run > devmgmt.msc). If I'm correct, the driver of the camera is not installed properly. In this case, locate the item in the list and select Update Driver. Make sure you have the driver installed, then set the wizard to search automatically and then, after the installation finishes, you should be able to use the camera.
