Uninstall and re-install the software on another pc

Hello, I ask you for support for a doubt: I sold the software (Paragon Hard Disk Manager 15 Professional) to a client's IT manager but now this person leaves the company; new IT manager asks me if it is possible to uninstall the software from the PC of the outgoing resource and install it again on another PC. Can you tell me if it's possible?
Thank you. :)

Best regards,
Ale

Don't you think that a license question is a typical case for a support request instead of a public forum request?
