This Code is not valid for this device - Error message - How do I fix this?

Hello,

I able to think that good to start from F-Secure Support Channel:

https://www.f-secure.com/en/web/home_global/contact-support (Chat/phone);

You able to ask them about your subscription and "why this code is not valid for certain device";

General Knowledgebase-article:

https://community.f-secure.com/t5/F-Secure/Why-doesn-t-my-F-Secure-Freedome/ta-p/79111

probably did not cover your situation, but you able to re-check it too (about some meanings);

Thanks!
