Nathan Smith Posted January 5, 2021 Report Share Posted January 5, 2021 My computer recently would not let me login after a Windows 10 update, forcing me to reset windows, which deleted my programs. Upon reinstalling Nitro PDF (which I have purchased and been using for my law practice), Nitro would not accept my Serial Number. It gave me an error, "The serial number entered does not exist." Upon going through the self-help system, I used the Nitro deactivation portal. It said I had 2 activations, and 2 allowed. I deactivated and attempted to enter the Serial Number into the activation, which did not work, and subtracted an activation. I attempted the process again, and now have 0 activations allowed. Upon reading similar posts, I am guessing the Serial Number did not work because it was for a previous version of Nitro. However, now I have 0 activations allowed, and may not be able to activate using my serial number even if I downloaded the right version. I unsuccessfully attempted to post this on December 28. Assistance would be helpful. Thanks, -Nathan Link to comment Share on other sites More sharing options...

Official Nitronaut Allain Umailin Posted January 7, 2021 Official Nitronaut Report Share Posted January 7, 2021 Hello @Nathan Smith, Thank you for the private message. Please be informed that 'The serial number entered does not exist' means the serial number you are trying to activate is for a different version of Nitro Pro. Looks like we need to uninstall the current version of Nitro Pro on your computer and install Nitro Pro 12. We then activate it using your serial number. Kindly follow these steps: 1. Uninstall Nitro Pro from your computer by going to Control Panel > Programs > Programs and Features then reboot the machine. 2. 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. 3. Download your Nitro Pro 12 using these offline link/s: x32 http://install.nitropdf.com/professional_12163574/en/retail/nitro_pro12_ba_x86.msi x64 http://install.nitropdf.com/professional_12163574/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 4. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activation and entering your serial number. Thank you for choosing Nitro and I hope this helps.
