Not able to upgrade to Nitro Pro 14

Karl Dohm

Recommended Posts

I purchased the bundle when on Nitro 12 to Nitro 13 and it promised a free upgrade to Nitro 14 when it came out.  See below.  Please put my product serial number in your database as eligible for upgade to version 14.

When I tried to upgrade to version 14 I got: We were unable to validate your serial number. Please ensure you entered it correctly.

Greetings @Karl Dohm

Thank you for reaching out through our Community Forums!

I have taken the necessary adjustment to ensure that you can proceed with upgrading your version 13 license to 14. However, the upgrade offered for this serial number is at a discounted price and not free due to the inactive/expired Product Updates. 
A support case will be created on your behalf to further discuss your upgrade options. Kindly wait for the support case to be created. 

Kind regards,
