Paul Long Posted March 26, 2021 Report Share Posted March 26, 2021 My computer recently crashed so I had to install NitroPro again and can't get it to activate. I get this error: "There was an issue with the activation certificate." Link to comment Share on other sites More sharing options...
Official Nitronaut Leslie V Posted March 29, 2021 Official Nitronaut Report Share Posted March 29, 2021 Hello Paul, Thanks for reaching out to us! Please completely uninstall Nitro and then delete all previously downloaded installers from your Downloads folder. Please reboot and then reinstall the latest Nitro Pro 13 update from this page: https://www.gonitro.com/nps/product-details/downloads After reinstalling, please try activating again. Let me know how that goes. Cheers! Link to comment Share on other sites More sharing options...
Paul Long Posted April 13, 2021 Author Report Share Posted April 13, 2021 This didn't work. Any other suggestions? Link to comment Share on other sites More sharing options...

Paul Long Posted April 16, 2021 Author Report Share Posted April 16, 2021 How do I paste the screenshots in here? It won't let me paste it. Can I email it to you? Is there a phone # I can call to get help? I've been without NitroPro for 3 weeks! I use it daily with my job and it's frustrating that I'm unable to use it right now!!

Official Nitronaut Leslie V Posted April 16, 2021 Official Nitronaut Report Share Posted April 16, 2021 (edited) Hello Paul, Let's do a cleanup and then reinstall the latest update. Please use the tool I have provided below to remove all files associated with Nitro Pro and reboot your system.https://install.nitropdf.com/professional_13381739/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 When your system is back up, close all your open applications and install Nitro Pro 13.38 from one of the links below: 64 bit 32 bit I hope this helps! Please let me know how that goes. Edited April 16, 2021 by Leslie V. Link to comment Share on other sites More sharing options...
