Eamonn Posted December 4, 2019 Report Share Posted December 4, 2019 Hello, I have changed to a newer laptop. I have deactivated NitroPro (pre-2012 version; 2 activations on earlier laptops) using the licensing portal. When I proceed to activate using my license number, I get the error message "you have attempted to activate Nitro Pro with a serial number from another version...". Any help would be great. Thanks Eamonn Link to comment Share on other sites More sharing options...
