Aravind 0 Report post Posted September 1, 2019 Hi, I've de-registered Nitro Pro on my previous computer and also checked in the licensing portal https://licenses.gonitro.com/prd/portal that Number of Activations = 0 but I still get an error 23 license number already used. Can anyone help as i am unable to create a support ticket either. Regards Share this post Link to post Share on other sites
