seb a 0 Report post Posted November 2, 2020 (edited) I have an existing Nitro Pro subscription and serial which appears to be version 11 (see also cleverbridge reference number: 138****** if you wish to cross check). I had to uninstall some programs including Nitro. When I went back to reinstall there was no version 11 on your website. I installed version 13. I am now unable to activate. I have deactivated and attempted to activate as well (https://licenses.gonitro.com/prd/portal) but understand that serial may only work for specific versions. I do not wish to upgrade if there are additional costs - the previous version was working fine. Please advise on how to reactive. Thank you Edited November 4, 2020 by Reymund G.

Please uninstall Nitro Pro 13 then download Nitro Pro 11 from the following location:https://kb.gonitro.com/knowledgebase#/search/installer/000004464 Go to the Nitro Pro 11 section then download the Nitro Pro 11 installer that matches your Windows installation (32bit or 64bit). Once Nitro Pro 11 is installed, you should be able to activate it using your version 11 serial number. Kind regards, Share this post Link to post Share on other sites
