Please clear all your downloads folder or delete all downloaded Nitro installers. Uninstall Nitro Pro from your computer by going to Control Panel > Programs > Programs and Features then reboot the machine.Ģ. We then activate it using your serial number. Looks like we need to uninstall the current version of Nitro Pro on your computer and install Nitro Pro 12. 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.
