tina_in_az Posted November 22, 2018 Report Share Posted November 22, 2018 Friends. I own a license for 2 Nitro Pro installs and have had it installed on a Surface Pro for the past 6 months. I just purchased a 2nd Surface Pro that I'm trying to install it to. I unwittingly downloaded v12 and installed it, then when attempting to activate the license discovered that my license was for v11. To remedy my mistake I uninstalled v12, rebooted, downloaded v11 and ran the install wizard but midway through the process the wizard stops and displays "Wizard failed". Any ideas?

Official Nitronaut Allain Umailin Posted November 22, 2018 Official Nitronaut Report Share Posted November 22, 2018 Hello @tina_in_az, Thank you for reaching out to us through our Community Forums! Let us try some troubleshooting by referring 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. Run MS FixIt to uninstall your Nitro Pro 12: https://support.microsoft.com/en-us/help/17588/fix-problems-that-block-programs-from-being-installed-or-removed 3. Reboot your machine. 4. 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 installed in that folder and you may pick-up one of the older builds instead of the newly downloaded package. 5. Download and install Nitro Pro 11.0.8.460 using below offline installers: x64 http://install.nitropdf.com/professional_1108470/en/burn/nitro_pro11_ba_x64.msi x32 http://install.nitropdf.com/professional_1108470/en/burn/nitro_pro11_ba_x86.msi If you are not sure which to pick, this will help: http://kb.gonitro.com/knowledgebase#/search/64/000001874 6. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activation and entering your serial number. Thanks for choosing Nitro Pro and I hope this helps! Link to comment Share on other sites More sharing options...
