Recommended Posts

I changed computers and I want to activate a Nitro Pro license. On the Site  Number of Activation is 0 and when I Click on the Deactivate-button the following message appears "Please select devices to deactivate" and nothing happens. I can't activate the license in my freshly installed program. When I try t enter the serial number in the application, it errors out and asks me to come to the website. I am stuck i this loop. Please advise.

Hello @AK Varma,

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 and to further assist you, 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'.

This matters because our business installers are different from the online ones.

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

Hello @AK Varma,

Thank you for the private messages.

Looking at our Activation Portal, there is nothing to deactivate because below serial numbers has the following status:

23460x-xxxxxx-x70526 with 0/2 activation
23460x-xxxxxx-x33881 with 0/2 activation
23460x-xxxxxx-x63253 with 0/2 activation

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 have shut down the one your older version of Nitro Pro runs on so please clear all your Downloads folder or delete all downloaded Nitro installers. This step is important because we noticed that if you are saving all the installers and you download them in the same folder (like the downloads folder), the EXE can pick up any MSI installer in that folder and you may pick-up one of the older builds instead of the newly downloaded package.

Then install Nitro Pro 12.16.9.574 by getting the installer from this page:

https://www.gonitro.com/nps/product-details/downloads 

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:
https://support.microsoft.com/en-ph/help/15056/windows-32-64-bit-faq 

After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering the above serial numbers

Thank you for choosing Nitro and stay safe always!
