John_W Posted March 20, 2020 Report Share Posted March 20, 2020 Hi Folks, We have a 20 license activation key and I can currently see via the portal that only 6 keys are active, I've got a couple of users who are trying to activate but are getting a -23: Error License number already used, I've asked them to check the computer ID in the Activation / Advanced and they are both showing: Computer ID: 0000-0000-0000-0000-0000 Installation ID: 00000000000000000000xxxxxxxxxxxx (numbers replaced by x) I'm guessing that's likely the problem, they have tried installation and re-installing but the problem still persists. Any Advice please. Thanks -John Link to comment Share on other sites More sharing options...
