1. CC has no price for life. It is subscription only.
2. Subscribers can only get the current version and the one before (today, CC 2021 2020).
Anyone claiming to have price for life is trying to steal from you and install malware. Warning, scammers may contact you privately pretending to be Adobe staff. Adobe will never send you a private message asking you to email an account that isn't @adobe.com, or use Skype. Adobe never ask you for their password. These scammers want your Adobe info, credit cards, your money and control of your computer, please take care.
