A Sentinel Key is a physical USB dongle or a software-based "soft-key" produced by Thales (formerly SafeNet). It acts as a security lock for expensive software, ensuring that only users with the physical key or a valid license file can access the program. When you see "Sentinel Key Not Found," it means the software "polled" your USB ports or license manager and came back empty-handed.
