Nitro 12 deactivated for no reason and will not let me reactiviate

[Logan Verner]

I have owned it for years.  -24 activation error when I entered serial number today.  I was active on Friday and deactivated over the weekend.

Hello @Logan Verner,

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

Did the affected machine installed a major Windows Update prior to this issue? If yes, kindly note upon the upgrade of the operating system or installing a major Microsoft update, the Computer ID is changed, as it is comprised partially by the operating system. Once changed, this will no longer recognize the original installation causing the program to revert to trial mode.

As a courtesy of being a valuable customer of Nitro, 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 using below direct MSI links:

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:

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

Thank you for choosing Nitro and I hope this helps.
