Ive registered for and got the free licence for the latest Fusion Player - Version 13. However my iMac is on OSX 10.15 which only suppoerts Player V12. Ive downloaded V12 and installed it OK - but it's asking for the licence key and wont accept the one I got for V13. How can I obtain or swap my V13 licence for a V12 one. I understand that V12 had the free licencing option
