Troubleshooting

Upon encountering any issues, please make sure to do all the steps listed below.

0- Ensure you have enough space on your Hard Drive. 1- Always use our Full Installer. You can download it here. 2- Right-click on ERO.exe and set its Compatibility mode to Windows 7, if you're running Windows 10 or Windows XP Service Pack 3, if you're running Windows 7. 3- Right-click on ERO.exe and tick the box next to Run as Administrator. 4- Right-click on ERO Patcher.exe and tick the box next to Run as Administrator. 5- Be sure to grab the latest patch through ERO Patcher.exe. 6- Avoid installing the game to Program Files. Install the game in a custom path, eg. C:\Ragnarok\ERO 7- Disable Anti Virus software before installing and/or patching. (Especially in the case of Avast and McAfee) They often give false alarms, especially our modified ERO.exe client might trigger one. 8- Never install our Server files together with other Server files! Always prepare a clean folder. 9- Delete D3D8.dll, D3DImm.dll and DDraw.dll and then run the Setup.exe to reconfigure your ingame settings. This will remove our custom API wrapper and let the game natively run on your hardware. 10- Make sure you use the Website "Start Game" button to launch our client. Other methods of starting the client will not work!
