Hi @Scott Seaman

Thank you for reaching out to us through our Community Forums!

Please ensure that you install the latest build of Nitro PDF Pro 12 ( so you could successfully activate using your version 12 serial number.
The version and build can be located under the Help tab > About Nitro Pro. 

If you see that your installation is not on Nitro PDF Pro, please uninstall then install that build by downloading the installer from the following location: 
https://www.gonitro.com/nps/product-details/downloads - Click the 'Download Nitro Pro 12' link (not the Nitro Pro 13 link) 

After installing Nitro PDF Pro, activate it by going to the Help tab > About Nitro Pro > Activate. Enter the serial number then click the Activate button. 

If the activation issue persists, please provide the following:

1. Screenshot of the activation error message. 
2. The version and build of your Nitro PDF Pro. This information can be located under the Help tab > About Nitro Pro. 


In any case you are interested to upgrade your license (with a discounted price) to the latest version which is Nitro PDF Pro 13, you can do the upgrade through our Upgrade portal - https://www.gonitro.com/support/upgrade. 
Nitro PDF Pro 13 comes with significant stability and security improvements, as well as many feature enhancements, in particular in conversion and OCR functions. 

Kind regards,
