I have a new PC but I'm having trouble getting Nitro Pro to activate. I'm getting an actvation -24 error in Nitro. When I go through the help wizard it gets to a page (shown below) but there is nothing I can select before clicking deactivate. I'm guessing it wants me to select something but nothing is shown.

Version 12
Status Active
Number of Activations 0
Number of Activations Allowed 2
Deactivate

Hello @Andrew Jones,

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 (e.g. -2: Error - Bad parameter or -24 Error: Activation Error or -79: Activation Error). 

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 it by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering the same serial number 234600-xxxxxx-914265

Thank you for choosing Nitro and stay safe always!
