Hello,
Sorry to hear you are having issues. Usually if you install a product purchase via Steam using Steam application. Upon trying activation opn the new system, it will tell you that the software are currently activated on another system and ask you if you wish to deactivate that old activation? If you answer yes, it will than deactivate the old one and activate that app for your current system. Do you saw this popup message?
Thank you,
