Robyn Jarram 0 Report post Posted August 9, 2020 I've just got a new computer and Nitro keeps telling me that my serial number doesn't exit. I'm getting the serial number from my other computer therefore I know it exists. My records onscreen also say I have 2 possible activations but I have not activated anything therefore I know I have the ability to activate using the serial number. I have done the deactivation/reactivation process and it didn't work. I have also deactivated Nitro from my other computer. Please help me activate it on my new computer. Thanks, Robyn Share this post Link to post Share on other sites

This error usually means that the serial number you are trying to activate is for a different version of Nitro Pro. Your serial number is for Nitro Pro 12, please uninstall what you have and get the correct installer from the page below:https://www.gonitro.com/nps/product-details/downloads After installation, activate with your serial number. Please let me know how you go. Edited August 10, 2020 by Leslie V. Share this post Link to post Share on other sites
