Manoj Jain Posted January 8 Report Share Posted January 8 I just switched computers and installed Nitro Pro 7 on my new computer running Windows 11 Home. Unable to activate Nitro Pro even after I enter the Serial no - getting 'unknown error'. Any suggestions on how to proceed? Thank you Manoj Jain Link to comment Share on other sites More sharing options...
Official Nitronaut Leslie V Posted January 9 Official Nitronaut Report Share Posted January 9 Hello @Manoj Jain Thanks for reaching out to us! I am happy to assist you. Please note that we no longer support Nitro Pro 7 and its activation servers have been shut down. We recommend to upgrade to our latest version, V13, which comes with significant stability and security improvements, as well as many feature enhancements, in particular in conversion and OCR functions. To upgrade to Nitro Pro 13, please visit our upgrade page: https://www.gonitro.com/pro/upgrade Alternatively, you can upgrade to the latest build of Nitro Pro 12. Per our Sunset Policy, https://www.gonitro.com/nps/product-details/sunset-policy, we have stopped making feature enhancements to version 12 once we released version 13. You can find Nitro Pro 12 installer from the page below and activate it with your current Nitro Pro 7 serial number. https://www.gonitro.com/nps/product-details/downloads Please let us know if you need any further assistance.

Manoj Jain Posted January 9 Author Report Share Posted January 9 Thank you - I did download version 12 and tried to use my Version 7 serial no - it did not accept it. I receive the following message: -22 Error - wrong license no You have attempted to activate Nitro Pro with a serial number from another version. You can only activate this version of Nitro Pro with its matching serial no. Please advise. Thank you Link to comment Share on other sites More sharing options...

Manoj Jain Posted January 10 Author Report Share Posted January 10 Hi Leslie Found the correct version but unable to install - getting a message: Nitro Pro Setup Wizard has failed. Please advise. I am using Windows 11 Home - could that be an issue? Thank you Link to comment Share on other sites More sharing options...
