Unable to Re-activate


Recommended Posts


I had to re-install the OS due to a hardware failure of my laptop (Motherboard and few other things were replaced under warranty).

I tried to activate Nitro Pro 12 and it gives the following error: -23: Error - License Number Already Used

Please note that I already deactivated the product from following link: https://licenses.gonitro.com/prd/portal

Anyway to resolve this issue?

Thanks & Regards,

Hi @ASG-000,

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

An adjustment has been made on your Nitro Pro 12 license. Please try to activate again and it should be working now. 

Kind regards,

I have deactivated my license on my laptop and it shows 2 licenses available. When I go into NitroPro 12 and try to activate my license, it does not happen.
