Nitro 12 Activation

[Brennan Townley]

I am trying to activate my serial number on a 2nd computer and I keep getting an error that says "The serial number entered does not exist." even though I am copying the serial number directly from a working version of Nitro Pro. Help!

Hello @Brennan Townley,

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

In order to further assist you, could you please provide a screenshot of your 'About Nitro Pro' window under Help tab?

This window should show the exact build of the program and its serial number (format is 13.X.X.X, e.g. 13.2.3.26). 

Lastly, could you please provide the serial number of your Nitro Pro 12?

To send them via private message, hover your mouse on top of my name 'AllainU' and select 'Message'.

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

Hello @Brennan Townley,

Thank you for the private message.

Please be informed that 'The serial number entered does not exist' means the serial number you are trying to activate is for a different version of Nitro Pro. Looks like we need to uninstall the current version of Nitro Pro on your computer and install Nitro Pro 12. We then activate it using your serial number. Kindly follow these steps:
 
1. Uninstall Nitro Pro from your computer by going to Control Panel > Programs > Programs and Features then reboot the machine.

2. 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.

3. Download your Nitro Pro 12 using these offline link/s:

x32 http://install.nitropdf.com/professional_12163574/en/retail/nitro_pro12_ba_x86.msi 
x64 http://install.nitropdf.com/professional_12163574/en/retail/nitro_pro12_ba_x64.msi

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

4. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activation and entering your serial number.

Happy new year and I hope this helps.
