In some cases — especially for players using Windows 11 — problems with launching the game may occur. MuOnline is an old title, and newer versions of Windows can sometimes cause additional issues when trying to connect. Fortunately, the problem that appears on Windows 11 is easy to fix and allows players to get back into the amazing world of MuOnline.

What’s the issue?
Players trying to start the game may see an error message such as “Missing file: main” or “Missing file: main.premium.”

If you’re using Windows 11, follow the simple steps below to fix this issue and continue your adventure without interruption.

Another common issue is that MAIN.exe suddenly disappears from the computer — the game window closes automatically without any warning.
