Keep getting error when activating nitro Pro 12

[Garth Barrett]

I deactivated nitro pro 12 off of my old computer and continue to get an error when i try to activate it on my new computer. It's the 24 error. Is there anything i can do to get this activated?

Hello @Garth Barrett,

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

In order to further assist you, could you please provide the serial number of your Nitro Pro 12?

To send it via private message, hover your mouse on top of my name 'AllainU' and select 'Message'.

This matters because our business installers are different from the online ones.

Thank you very much in advance and I am looking forward to hearing back from you.
