Activation Problem

[Hasan Alf]

I followed the steps and reach the "deactivate" button. But when I clicked it a message popped up requiring me to choose the devices I wish to activate. But there was nothing to choose from.

Hi @Hasan Alf

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

I believe that you are referring to our licensing portal at https://licenses.gonitro.com/prd/portal 
If the Number of Activations shows 0 (zero), no need to click the Deactivate button. 

You can continue to use your existing serial number to another machine as long as you install the latest build of Nitro PDF Pro 12 which is 12.16.9.574.

The Nitro PDF Pro 12.16.9.574 installer can be located from the following location:
https://www.gonitro.com/nps/product-details/downloads - Click the 'Download Nitro Pro 12' link (not the Nitro Pro 13 link) 

After installing Nitro PDF Pro 12.16.9.574, activate it by going to the Help tab > About Nitro Pro > Activate. Enter your serial number then click the Activate button.

Kind regards,
