The recommended requirement for the game is Microsoft Windows® 98/2000/XP/Vista/7/8. Windows 10 or higher may recognize the game as a virus. If you send us an email at master@rowplayon.com with the error code, you may be able to get a more specific response. Also, trying a virtual machine is always an option.

same issue with me, I google and it seems that the Gameguard doesnt support for this game in windows 11 , hopefully ROW team will raise this issue to INCA.

@GM Better make announcement on this issue, not to upgrade the system to windows 11 and recommend to stay with windows 10.
