Activation on my new computer

Hi, I recently upgraded my computer & when reinstalling my Nitro Pro 12 it does not activate so I uninstalled it & installed Nito Pro 13 but with the same results. The window says Once you click “Deactivate”, you can activate your license immediately by entering the below serial number into Nitro Pro. It shows the serial no., Version: 12, Status: Active, Number of Activations: 0, Number of Activations Allowed: 2 

When I click "Deactivate" it says:  licenses.gonitro. com says    Please select devices to deactivate.

And of course, there are no devices to select.

Hello @Mohammed Hamdan,

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

To continue offering our customers the very best PDF tools, uninstall your current Nitro Pro through Control Panel\Programs\Programs and Features and reboot your machine.

After rebooting, 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 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 234601-xxyyzz-632501

Thank you for choosing Nitro and I hope this helps.
