ChrisC Posted February 15, 2018 Report Share Posted February 15, 2018 I am trying to deactivate an installation of Nitro Pro 11 on my old laptop and under the help>about window the key does not show up above the deactivate button. Is this a bug? How can I deactivate my key? I don't remember what the key was when I bought it. Link to comment Share on other sites More sharing options...
