For 'permanent authentication on installed PC' :

  • When the program is installed and executed for the first time, a unique number for the order number is registered and certified. You can register as many as the permitted number of authentications, and once authenticated, you can run offline without an online connection.
    This means that it can be permanently used on the installed and certified PC. When you reinstall from an authorized PC, if you are online, you will be authenticated without changing the number of authentications. However, please note that formatting is recognized as installation on another PC.
