Kristi Maritn 0 Report post Posted July 31, 2019 I have changed computers and cannot activate Nitro Pro on my new pc. I have deactivated on my old pc, but when I enter the Serial Number i get the message that Error #23 License already in use on another computer. I have waited more than 48 hours to try and reactivate my product. Share this post Link to post Share on other sites

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. Thanks for choosing Nitro Pro and I hope this helps! Share this post Link to post Share on other sites
