Schools can receive an invoice with my bank details for the school authority upon request.
After paying the registration fee, you will receive your personal serial number, which you enter in the File/Registration menu.
The program calculates your serial number from your name and place of residence and compares it with the number you entered. If both match, you will receive the message "Registration completed successfully"; otherwise, you will receive the message "Address does not match the serial number".
After successful registration, the note "For private use only" will be replaced by the licensee.
