Activation not possible

[Andres Soto Falkenahgen]

When trying to activate my nitro pro 12 license after switching computers, the activation portal is saying 0 licenses are activated and 2 are allowed. However, I cannot activate the product using my serial number. Any support is highly appreciated.

In order to further assist you, could you please provide the serial number of your Nitro Pro 12?

Hello @Andres Soto Falkenahgen,

Thank you for the private message.

To further assist you, I just made an adjustment on your license, so you can now activate your copy of Nitro Pro 12 by going to Help tab > About Nitro Pro > Activate, entering your serial number and clicking Activate.

We have a rare problem where occasionally Nitro can not create an ID on a computer and instead assigns it to be '00000000000000000000'. This ID causes a conflict on our activation server and will recover an error. If you have a computer that has this error, you can check Nitro Pro to see if it is the same computer ID through Help > About Nitro Pro > Activate > Advanced. 

Thank you for choosing Nitro and I hope this helps.

Hello @Andres Soto Falkenahgen,

Thank you for the private message.

Instead of deactivating and as a courtesy of being a valuable customer of Nitro, we want to make you aware of the change to your products that may affect its activation performance (e.g. -20: Error - Invalid license number or -24 Error: Activation Error). 

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 just install Nitro Pro 12.16.9.574 on your new computers using below direct MSI links:

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 same serial numbers.

Thank you for choosing Nitro and I hope this helps.
