What is Pace Interlok?
Pace also uses a Windows driver (the Pace Interlok driver) to implement software protection. Starting with DxO Optics Pro v5.1, this driver is no longer being used by DxO Optics Pro. This means absolutely no active or resident component runs on your system outside the DxO Optics Pro application. License management is now performed entirely within the DxO Optics Pro application.
