Gangledore 1 Report post Posted April 7, 2019 I have exactly the same problem. I have two activations available. I use Nitro on one desktop and one laptop. Had to re-install Windows on both. Through the licence portal I deactivate both machines. The install and activation on the desktop went fine, no problems at all. The installation went fine on the laptop but I can't activate, error 23 - License number already being used. Can you help? Many thanks. Share this post Link to post Share on other sites

Please check the activation again and let me know how it goes. Kind regards, Share this post Link to post Share on other sites
