warrenmb Posted December 16, 2019 Report Share Posted December 16, 2019 I installed Nitro Pro on a new computer. I followed all the necessary steps per the ticket instructions (deactivate etc.) and receive a message that the serial number entered does not exist despite showing 1 of 2 activations prior to selecting deactivate. I need to activate the trial, how to I remedy the issue? Link to comment Share on other sites More sharing options...
Official Nitronaut Allain Umailin Posted December 16, 2019 Official Nitronaut Report Share Posted December 16, 2019 Hello @warrenmb, Thank you for reaching out to us through our Community Forums! Since I am unable to pull-up your account, could you please provide the serial number of your Nitro Pro? This matters because our business installers are different from the online ones. Also, what build of Nitro Pro did you install? You can find this out by clicking on 'About Nitro Pro' under the Help tab (format is 11.X.X.X, e.g. 11.0.7.411) or you can go to Control Panel > Programs and Features. To send them via private message, hover your mouse on top of my name 'AllainU' and select 'Message'. Thank you very much in advance and I am looking forward to hearing back from you.

Official Nitronaut Allain Umailin Posted December 17, 2019 Official Nitronaut Report Share Posted December 17, 2019 Hello @warrenmb, Thank you for the private message. 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. Looks like we need to uninstall the current version of Nitro Pro on your computer and install Nitro Pro 11. 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 11 using these offline link/s: x64-bit: http://install.nitropdf.com/professional_1108470/en/burn/nitro_pro11_ba_x64.msi x32-bit: http://install.nitropdf.com/professional_1108470/en/burn/nitro_pro11_ba_x86.msi If you are unsure if your machine is using 32 or 64-bit, please refer to this link: https://kb.gonitro.com/knowledgebase/#/search/64/000003790 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!
