Leslie V. 0 Report post Posted October 2, 2019 Hello @D. Tompkins Thanks for reaching out to us! I am happy to assist you. Please uninstall the old version of Nitro Pro and install Nitro Pro 13. You can get the correct version 13 installers from this page: https://www.gonitro.com/nps/product-details/downloads After installation, you can activate by opening Nitro, click on the Help tab > About Nitro Pro > Activate and enter your Nitro Pro 13 serial number. Please let me know how that goes. Share this post Link to post Share on other sites
