Official Nitronaut Allain Umailin Posted January 25, 2021 Official Nitronaut Report Share Posted January 25, 2021 Hello @Christin Johnson, Thank you for reaching out to us through our Community Forums! In order to further assist you, could you please provide the serial number of your Nitro Pro? To send it via private message, hover your mouse on top of my name 'AllainU' and select 'Message'. This matters because our business installers are different from the online ones. Thank you very much in advance and I am looking forward to hearing back from you.

Official Nitronaut Allain Umailin Posted January 29, 2021 Official Nitronaut Report Share Posted January 29, 2021 Hello @Christin Johnson, Thank you for the private message. Please be informed that '-20: Error - Invalid License Number' 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 13. 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 13 using these offline link/s: x32 http://install.nitropdf.com/professional_13332645/en/retail/nitro_pro13_ba_x86.msi x64 http://install.nitropdf.com/professional_13332645/en/retail/nitro_pro13_ba_x64.msi 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.
