After registration

[4work2test]

Hello.
After installing FreeOffice, I immediately registered the product via my email address. Will I receive messages about the need to re-register the product or something like that? If so, how often?
Or after registration I will be able to use the product without any problems and such messages will not bother me anymore?

No re-registration is required. After completing your initial registration, you'll receive a free product key to activate your software. Simply use this key to activate.
