-23: Error - License number already used

[Lucio]

I made an update to windows 10 release 1903. Aufter this I must reactivate Nitro, but when I try to do this I became the error: -23: Error - License number already used

 It said it couldn't activate because there were no available licenses. I headed to the activation portal and deactivated the licenses we have. Confirmed deactivated. 

-23: Error - License number already used.

Hello @Lucio,

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

Kindly note upon the upgrade of the operating system or installing a major Microsoft / Windows update, the Computer ID is changed, as it is comprised partially by the operating system. Once changed, this will no longer recognize the original installation causing the program to revert to trial mode.

In order for me to further assist you with your concern, could you please provide the serial number of your Nitro Pro?

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

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

Hello @Lucio,

Thank you for providing your serial number.

I just made an adjustment on your license, so you can now activate your copy of Nitro Pro by going to Help tab > About Nitro Pro > Activate, entering your serial number and clicking Activate.

Thank you for choosing Nitro and I hope this helps!
