-24 Activation error

We are trying to move Nitro Pro from one computer to another.  However, when you try to deactivate it, it gives an error.  "-24 Activation Error  Nitro encountered some issues while attempting to activate."

When trying to create a support ticket, it doesn't allow us, and instead it redirects to https://licenses.gonitro.com/prd/portal

Our serial says it has 0 activations, and 2 activations allowed, and when trying to deactivate it asks to select a device, but there isn't one to do so.

license number is 234600-xxyyzz-626152

Thanks and kind regards.

Hello @alyza balmores,

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) and to continue offering our customers the very best PDF tools, please install Nitro Pro using the below offline English MSI 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:

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

Thank you for choosing Nitro and I hope this helps.

Hi, I've tried downloading the installer and it 'can't be downloaded securely'. I have Nitro Pro 12 already and run on Windows 11.
