Cacquaotta Posted March 4, 2020 Report Share Posted March 4, 2020 My Nitro Pro has switched to trial mode and I am unable to reactivate with my original serial number and activation code. I've followed these instructions from another forum post and am still unable to activate: "To further assist you, you need to uninstall Nitro Pro 13 so we can reinstall your Nitro Pro 12. Please refer to these steps: 1. Clear the content of the directory under C:\users\your_username\Appdata\local\temp. For whatever reason, not all temp files automatically remove themselves and is NOT usually caused by Nitro Pro files. 2. Uninstall Nitro Pro 13 by going to Control Panel \ All Control Panel Items \ Programs and Features and reboot your machine. 3. 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. 4. Download and install Nitro Pro 12.16 using below offline installers: x32 http://install.nitropdf.com/professional_12163574/en/retail/nitro_pro12_ba_x86.msi x64 http://install.nitropdf.com/professional_12163574/en/retail/nitro_pro12_ba_x64.msi If you are not sure which to pick, this will help: https://kb.gonitro.com/knowledgebase#/search/64/000003790 5. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate and entering your Nitro Pro 12 serial number. Thank you for choosing Nitro and I hope this helps!" Is there something else that I can try? Link to comment Share on other sites More sharing options...
