alexlinton 0 Report post Posted January 4, 2020 I entered my serial number in the 'find license' field and it found it and shows as 2 available activations after deactivating the current machine. Now I am trying to enter it in Nitro Pro's activation and the error message says my serial number doesn't exist. Can you please help? Share this post Link to post Share on other sites
AllainU 0 Report post Posted January 4, 2020 Hello @alexlinton, Thank you for reaching out to us through our Community Forums! Before continuing, I should let you know that we no longer support Nitro Pro 11 or older. It has been discontinued as documented in our Sunset Policy: https://www.gonitro.com/support/sunset-policy As a courtesy, 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. Alternatively, if you were interested in upgrading your license to Nitro Pro 13 with VIP Access (formerly Software Assurance), kindly access our Upgrade Portal and enter your Nitro Pro 11 serial number: https://www.gonitro.com/pro/upgrade Thank you for choosing Nitro and I hope this helps!
