What kind of software protection is available for ARCHLine.XP?

Hardware protection (USB key available separately).

A hardlock key or dongle is a unit connected to a USB port and allows you to run the program on one machine at a time. It provides more flexibility because the program license can be easily run on another computer by moving the dongle to the next computer.
The dongle can only be purchased for a perpetual license, and one license can only be accessed by a single dongle.

Software key:

The software key allows you to use the software on a computer that has the software installed and registered with a serial code. To transfer the license to another computer, you must deactivate the software and then register with the same serial code on the other computer.
