Each Chief Architect software license uses a security system that allows the license holder to install the program on whatever computers they wish and then run the program on one computer at a time.
Software Lock Security is now the only security option for Chief Architect users. It is internet-based and allows you to easily transfer the license from one computer to another. Simply turn off the license on the computer you are using and start the program on another computer while connected to the internet. Software security does require internet access approximately once every two weeks for license verification.
The discontinued Hardware Lock Security used a small USB device called a hardware lock that attaches to a USB port on your computer. The lock had to be in place in order for Chief Architect to operate. Hardware Lock Security is now discontinued.
