This did the trick. I downloaded all cores and didn't verify the correct associations. Thank you very much. ?

Same issue here. I bought a license today and now I have this frustrating issue. I can start retroarch from the commandline without a problem: retroarch.exe -L "L:\LaunchBox\Emulators\RetroArch\cores\fbneo_libretro.dll" "L:\LaunchBox\Games\Arcarde\..." In launchbox nothing happens. I additionally disabled the "hide console option" to examine the output but it did not open.
