Jerry Juenger 0 Report post Posted October 9, 2020 I had to use Windows Restore and now I'm being asked to activate my copy of Nitro Pro. I have a key, but this certificate stuff isn't showing up. Can someone help me get my Nitro Pro Registered so I can use it again? Share this post Link to post Share on other sites
AllainU 0 Report post Posted October 9, 2020 Hello @Jerry Juenger, Thank you for reaching out to us through our Community Forums! Based on the screenshots you have provided, you were offered to manually activate the program after clicking Activate button and it is not generating the activation certificate. At the moment, we are still investigating this behavior and to further assist you in troubleshooting this issue, kindly follow 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. Kindly note Appdata folder is hidden and to unhide it, please refer to this article https://cybertext.wordpress.com/2012/05/29/cant-see-the-appdata-folder/ 2. Download and run our Clean Up utility to uninstall your Nitro Pro: http://install.nitropdf.com/professional_13263505/install-cleanup/install-cleanup.zip NOTE: This clean-up tool will erase any existing signature files within Nitro so please save them to another location before using the clean-up tool in order to keep them. Please see this link for backing up custom stamps/signatures: https://kb.gonitro.com/knowledgebase#/search/stamps/000004307 3. 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 13.26 using below offline installers: x32 http://install.nitropdf.com/professional_13263505/en/retail/nitro_pro13_ba_x86.msi x64 http://install.nitropdf.com/professional_13263505/en/retail/nitro_pro13_ba_x64.msi 5. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering your serial number Thank you for choosing Nitro and I hope this helps.
