you should translate the read me inside the rar, there are instructions there.
In my google is like that:
1. In the keygen type "your name" in the format xxxx-xxxx-xxxx (any letters or numbers, for example 12qw-34as-56zx), insert the following "Device ID"
(You can read it in OziCE, click: File-Help-License Info) and click on the "Key"
2. In OziCE, in the input window of registration data (File-Help-Enter License Code) insert the name and the generated code. When you finish click OK.
3. Should display on the screen that the key is held and the program is not in the Demo.
