Greetings @Gary Williams

Thank you for reaching out through our Community Forums!

If you have purchased the license online, our merchant (CleverBridge) sends an email that has an Invoice Receipt and it contains the serial number. 
Please provide the email address you used to purchase it so we can search for the purchase record. 

Note: 
Please note that we no longer support Nitro Pro 12 and older versions and its activation servers have been shut down. Thus, any activation or deactivation attempt on these versions will no longer work. 
We recommend upgrading to our latest version, Nitro PDF Pro 14, which comes with significant stability and security improvements, as well as many feature enhancements, in particular in conversion and OCR functions. 

Kind regards,
