Need help activating Nitro Pro 12 on a new computer.

Mike Huddy

Recommended Posts

I recently built a new computer and deactivated Nitro Pro 12 on the old machine, and something didn't go correctly. During the deactivation process I was directed to open www.nitropdf.com/activation that redirects to www.internetactivation.com which refuses to connect. Though Nitro Pro is no longer active on the old computer.

I installed Nitro Pro 12 on the new computer, submitted a support ticket, chose "Activation", and entered my license. The results screen showed that the status was "active".  When I picked "Deactivate" the system responds by asking me to "Please select devices to deactivate" but there is no menu showing any devices.

How can I activate Nitro Pro 12 on my new computer?

Hello @Mike Huddy,

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

We want to make you aware of the change to your product that may affect its activation performance.

To continue offering our customers the very best PDF tools, we have upgraded our servers and has shut down the one your older version of Nitro Pro runs on so please install Nitro Pro by getting the installer from this page:


If you are getting the 'Nitro Pro Wizard has failed' message using our .exe package, it is because it requires a stable Internet connection to download installation files so please use offline English MSI packages:

x32 http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x86.msi
x64 http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x64.msi 

To know if you have 32-bit or 64-bit, please refer to this article:

After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering the same serial number 234601-xxxxxx-805244

Thank you for choosing Nitro and I hope this helps.
