Problem Activating NitroPro 12

[Pier Massa]

I'm having serious issues activating NP12 - I have a correct serial number and the status is active - it says I have 2 activations allowed by I cannot seem to get it activated and I'm having trouble getting the download links for 12 to work. I had downloaded 13 but it would not activate at all... so I'm feeling stuck. Can you please help. Thank you, Pier

Hello @Pier Massa,

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 shutdown the one your older version of Nitro Pro runs on so please refer to these steps:

1. Clear the content of the directory under C:\users\your_username\Appdata\local\temp. For whatever reason, not all temp files automatically remove themselves and is NOT usually caused by Nitro Pro files. Kindly note Appdata folder is hidden and to unhide it, please refer to this article https://cybertext.wordpress.com/2012/05/29/cant-see-the-appdata-folder/ 

2. Download and run our Clean Up utility to uninstall your Nitro Pro:  http://install.nitropdf.com/professional_13440896/install-cleanup/install-cleanup.zip

3. 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.

4. Download and install Nitro Pro 12.16.9.574 using below offline installers:

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 

5. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering your serial number 234601-xxxxxx-009071

Thank you for choosing Nitro and I hope this helps.
