have you admin rights at your computer? Are you sure that firewall does not block the communication with activation server?
Did you also try offline activation?
Yes, I have admin rights.
Also offline activation shows same result when I pressed xml save button.
What is the meaning of FNP error code? Can you clarify it?
For activation, what does the S32DS program do?
I am not license expert, so I cannot tell you what is the internal process of the activation. I will contact someone, who can help you more with your issue.
