Helix Systems 0 Report post Posted March 23, 2020 Hi, Support I am having an issue activating Nitro PDF Pro 12 on a Windows 10 workstation. I checked and re-checked the license on your website and current activation is 0. I tried using another available serial key and still getting the :23 Error License number already used. I was able to activate on a test workstation without any issues. I saw in the forum that this happens when the software was installed it did not generate a proper Computer ID which makes sense because when I was combing through the registry I did see an entry where there were all 0's. Please let me know if you are able to fix this on your end. Thank you Douglas Ngai, Share this post Link to post Share on other sites
