Well, this is the way this works:
-First you will going to install VeriFire Tools
-In the program, there's an option to generate an .HID file
-This file is unique for your configuration (computer, mother board, hard drive, operative system)
-You will going to summit this file to Notifier
-Notifier will replay with a "license" file
-This "license" file will be inserted in your VeriFire Tools and you will going to be able to use it.
-This license is valid for 2 years. After 2 years you have to request it again. After 4 years you should go to the course to get your certification again.
Do not swap a working HDD with VeriFire Tools from one computer to another; this won't work
