Launchbox not running games in MAME/RetroArch and other emulators in Troubleshooting Posted January 31 Actualization! After I re-installed windows and installed LB / BB completely clean, I still had the same problem, so I decided to buy the paid version of kapersky and examine my roms, in case they were corrupt or damaged. As a result, kapersky did not give me any virus messages, but when I launched LB it showed me several permission messages that I accepted, including some registers in REGEDIT, after giving yes to everything. now everything works without problems !! I dont know exactly why but it seems to be that launchbox cannot make right permission in some versions of windows Close the Topic!
