If you have a Forex Tester 4 (or 3) license, you can use the same registration key on a few computers. The license allows you to install the software on your PC at home and, say, on a laptop at work. You’ll be able to run the program on the PC when you are not working with it on the laptop. Working with Forex Tester on both machines simultaneously is not possible.

Your Forex Tester 2 registration key will work for one machine only. The software is attached to your computer and cannot be registered with the same key on another device. 

You can move Forex Tester 2 to another computer in case your PC has crashed or you bought a new PC
