Barry Rudolph 0 Report post Posted May 5, 2020 Hi -- I just got a new laptop, and deactivated my older serial numbers both from the app and then using your subscription manager. I have 0 activated licenses out of a potential of 2. However, when I input my serial number into the app I get an Error 23 saying my serial numbers are used. Please help or send me a new license number. Thank you Barry Share this post Link to post Share on other sites

To further assist you, I just made an adjustment on your license, so you can now activate your copy of Nitro Pro by going to Help tab > About Nitro Pro > Activate, entering your serial number and clicking Activate. Thank you for choosing Nitro and I hope this helps! Share this post Link to post Share on other sites
