Deborah Branham Posted February 17 Report Share Posted February 17 So my old PC has 10.5.0.26 and is licensed, when I try to deactivate the license it gives me error -24 and asks me to open a support request but I cannot because it says "Please enter a valid serial number" when I put my valid serial number in in the process of opening a support request. I installed 10.5.9.14 on my new PC and it will not take my serial. How do I get by this hurdle? Link to comment Share on other sites More sharing options...
