I’ve downloaded and istalled 8KPlayer, and try to register software, but it’s impossible, there is no registration dialogue. I’ve followed your instructions (NOTE: For those who have installed and activated 8K Player before and don’t see any registration dialog, simply go to C: drive in MY COMPUTER and type %APPDATA% into the search bar at the top. Then turn to IVSCAT folder and delete the 8K_PLAYER_FROM_DIMO_STUDIO(-1) file. After that, run 8K Player again and you will be asked to register it.)but in my Pc there is no IVSCAT folder…pls help or i must unistall this good software. thanks
