Christos Philippou Posted May 26, 2022 Report Share Posted May 26, 2022 Hi, I recently re-formatted my computer and had to re-install nitro pro 12. I tried to re-activate it using my serial number, but the system wouldn't allow me to. I tried to de-activate it also, but again the system wouldn't allow me to. Please help!

Official Nitronaut Allain Umailin Posted May 26, 2022 Official Nitronaut Report Share Posted May 26, 2022 Hello @Christos Philippou Thank you for reaching out to us through our Community Forums! To further assist you, could you please provide the serial number of your Nitro Pro 12? 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...

Official Nitronaut Allain Umailin Posted May 27, 2022 Official Nitronaut Report Share Posted May 27, 2022 Hello @Ben Whittaker, Thank you for reaching out to us through our Community Forums! We want to make you aware of the change to your product that may affect its activation performance (e.g. -2: Error - Bad parameter or -24 Error: Activation Error or -79: Activation Error). To continue offering our customers the very best PDF tools, we have upgraded our servers and have shut down the one your older version of Nitro Pro runs on so 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. Then install Nitro Pro 12.16.9.574 by getting the installer from this page: https://www.gonitro.com/nps/product-details/downloads If you are getting the 'Nitro Pro Wizard has failed' message using our .exe package, it is because it requires a stable Internet connection to download installation files so please use offline English MSI packages: x32 http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x86.msi x64 http://install.nitropdf.com/professional_12169574/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 After installation, you can activate it by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering the same serial number 234600-xxyyzz-904530 Thank you for choosing Nitro and stay safe always!
