Not able to activate after changing computer

[Antoine Ortolan]

Good day 
I have gone through the steps proposed when you go through the ticket, but once i reach the Deactivate option, i am told to choose a device to deactivate and from there i do not see how to progress. 
Any suggestions ? 
Thank you

Hello @Antoine Ortolan

Thank you for your message - I can help you out.

We have upgraded our activation servers. Please install the latest Nitro Pro 12 update (12.16.9.574) so you can reactivate successfully:

Then activate with your Nitro Pro 12 serial number.

I hope this helps!
