GSP 0 Report post Posted December 8, 2017 I deactivated my Nitro Pro 9 license from my old computer and tried to activate it to my new laptop but am getting error code 23 although I have no other active installation. How can I resolve this issue? Thank you Share this post Link to post Share on other sites
Ramon 0 Report post Posted December 9, 2017 I've got the same problem... I can't deactivate my former Nitro license as I formatted my hard disk due to a windows failure. How can I get back my license working? Share this post Link to post Share on other sites
Mario K. 0 Report post Posted December 10, 2017 @Ramon please try again. I've adjusted your license. I highly suggest to upgrade to Nitro Pro 11 since we don't support customers on previous versions with no Software Assurance any more. @GSP please send me a PM with your serial number. I was not able to find any purchase records under your email address. Share this post Link to post Share on other sites
