Moved computers not activating 12 results to -24 Activation Error

[Kristine Bradley]

Hello, I have a 12 Pro license - 234600-xxxxxx-717457

I moved to another computer.  I went through the help process for activation.  It says I have 2 activations allowed.  When I try to use them I get a -24, Activation Error.  

Thanks,

Kristine Bradley

Hello @Kristine Bradley,

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

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

After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering the same serial number 234600-xxxxxx-717457

Thank you for choosing Nitro and stay safe always!

Hello @Joshua Beaver,

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

To further assist you, please refer to these steps:

1. 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.

2. Download and run our Clean Up utility to uninstall your Nitro Pro:  http://install.nitropdf.com/professional_12169574/install-cleanup/install-cleanup.zip

3. Install Nitro Pro 12.16.9.574 by getting the installer from this page https://www.gonitro.com/nps/product-details/downloads 

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

Thank you for choosing Nitro and I hope this helps.
