Leslie V. 0 Report post Posted February 4, 2020 Hello @PLH-Fly Thanks for contacting Nitro! To upgrade to version 13, please proceed to the following web page, https://www.gonitro.com/pro/upgrade Enter your serial number one at a time and follow the prompts to receive a new Nitro Pro 13 serial key and installation files. Please note, the serial number that belongs to Patrick is no longer valid. That has been upgraded to Nitro Pro 10 a few years ago so that can no longer be used. Please use your Nitro Pro 10 key instead. Hope that helps! Share this post Link to post Share on other sites
