I recently re-installed my lightroom 6 to my pc and now I'm getting a notification that my serial number is already in use by the maximum allowed computers, is there a way for me to deactivate another computer?
Contact Adobe. Say you need an "Activation Count Reset." Use those EXACT WORDS, first. 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.
