Issue

If you receive an error message about server error during activation\registration attempt (locally or in License Manager), then Firewall or Proxy server can block access to our activation server or ports the product uses are closed.

https://registration2.abbyy.com 
https://registration.abbyy.com 
https://go.abbyy.com  

USA:

https://activation.abbyy.com 
https://registration.abbyy.com
https://go.abbyy.com  

2. Port 443 should be opened.
