david005 Posted February 19, 2020 Report Share Posted February 19, 2020 Hi, I am trying to move a license of Nitro 9 over to another computer and when I try to deactivate it off the old computer I receive an Invalid license number error (error 20). This is odd since the license serial number is already entered and was validated when I bought the software long ago. Please help me. THanks.
