Hi, I am trying to access my nitro pro on a 2nd pc.  The version I have is the old Nitro PDF Professional 6.2.3.6 - I am inputting the serial number and it is telling me it does not exist.

Please provide your serial number so we could check its record and status. 
You can send the serial number here and we will hide it before making the post in public.

Thank you @caragh@elecoservices.com

To successfully activate using that license, please make sure that you install Nitro PDF Pro 12 (12.16.9.574). 
The installer can be located from the link below:

https://www.gonitro.com/product-details/downloads - click the 'Download Nitro Pro 12' link.  

After the installation, navigate to the Help tab > About Nitro Pro. If it says Nitro Pro 12.16.9.574, click the Activate button then enter your serial number. 

The activation should work since old serial numbers were migrated to the new activation servers. This allows the old licenses to activate the latest build of Nitro PDF Pro 12.

Kind regards,
