Kelvin V. 0 Report post Posted August 8, 2018 Hi @Michael Fahey, Thanks for posting on our Community Forums! Error 22 means that the serial number you are trying to activate is for a different version of Nitro Pro. For a list of all available installers, please head to the following link: http://kb.gonitro.com/knowledgebase#/search/installer/000001632 Note: If you do not know which version of Nitro you are licensed for, you can check the information you received when you purchased Nitro.
