deactivate requests to select device, I can not see where to select the device


Recommended Posts



My computer crashed, big time. No access to the hard drive.

I have a new computer but sorely need to use "nitro". I have my serial number but when I try to deactivate I get

"Please select devices to deactivate."
I have looked everywhere to select the device but there is nothing to select.

Version 12
Status Active
Number of Activations 0
Number of Activations Allowed 2


I would really appreciate help solving this issue since I really need to be able to use Nitro.

Thanks in advance

Hello @avieladeitch,

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

Instead of deactivating through our Activation Portal and to continue offering our customers the very best PDF tools, we have upgraded our servers and has shutdown the one your older version of Nitro Pro runs on so please install Nitro Pro on your computer with a new hard-drive by getting the installer from this page:


After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering the same serial number 23460x-xxxxxx-409230

Thank you for choosing Nitro and I hope this helps.
