Shonnie Lavender Posted April 12, 2021 Report Share Posted April 12, 2021 I'm getting the same 401 error message. All I have to do is click "OK" and the program works but I'd prefer to skip this step. I just upgraded to version 12 (from 9) and have a 64-bit computer. Is there a different update I need to install than the one listed above? Link to comment Share on other sites More sharing options...
Official Nitronaut Allain Umailin Posted April 13, 2021 Official Nitronaut Report Share Posted April 13, 2021 Hello @Shonnie Lavender, Thank you for reaching out to us through our Community Forums! In order to further assist you, could you please provide a screenshot of your 'About Nitro Pro' window under Help tab? This window should show the exact build of the program and its serial number (format is 12.X.X.X, e.g. 12.0.0.112). Lastly, could you please provide the serial number of your Nitro Pro 12? To send them 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. Link to comment Share on other sites More sharing options...
