johnnymorls 0 Report post Posted February 13, 2020 I am trying to install Nitro Pro on a new laptop. However, when I enter the serial number I get an error message saying the serial number does not exist. I currently have Nitro Pro installed on one laptop which I want to keep it on. I also have it installed on an old desktop which has died and does not work. So I want to transfer my licence from the old desktop to my new laptop. I have followed the instructions on the support page to deactivate and then activate, but I get the same error message that my serial number does not exist. Please can you help.

I checked and your serial number is for Nitro Pro 11, so please install that version. https://kb.gonitro.com/knowledgebase#/search/installer/000004464 Cheers!
