Having trouble? If the client crashes or shows errors, try running it as administrator, turning off your antivirus for a moment (false alarms are common with RO clients), or downloading again from a different mirror. You can also ask for help on our Discord or in the Service Desk.

Antivirus warning: Some antivirus programs may flag the game client as suspicious. This is a known false alarm with Ragnarok Online clients. Add the Trinity Classic-RO folder to your antivirus exclusions list.
