By default Windows 8, 10, and 11 require that all device drivers have a digital signature. Some Dino-Lite models such as AM211, AM311(S)(H), AM313, AM411, and AM413 are older than Windows 8 and do not have a digital signature. To install these models on Windows 8 or above, the requirement for drivers to have a digital signature must be temporarily disabled.
