YSCHLM 0 Report post Posted November 26, 2019 Hi there, I have just purchased Nitro Productivity Suite for Nitro Pro 13. The serial number has been sent to my email and I tried to activate it on the program but wasn't able to do so. The ACTIVATE NOW button and the ACTIVATE menu don't seem to be working as well. I followed the un-installation and re-installation methods written on the HELP section on this forum but it's the same. It's really confusing and hope someone could help me here. Thanks.

Leslie V. 0 Report post Posted November 26, 2019 Hello @YSCHLM, 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 serial number. Please let me know how that goes. Share this post Link to post Share on other sites
