SBERKLEY  While Peak Pro 5 required an included USB key in order to operate, version 5.2 now utilizes a non-hardware based method of copy protection, offering greater flexibility for customers interested in retaining the use of their USB ports for other peripherals. For Peak Pro 5 customers who prefer the USB key, version 5.2 retains this compatibility. Although Peak Pro 5.2 no longer requires or includes a USB key, customers may order it on request from BIAS should they desire a hardware alternative to the new software based authorization system.
