🛠 How to Install and Run MU Online on Windows

To enjoy a smooth game experience, follow this simple setup guide. We provide 3 types of game client packages – choose the one that suits you best:

1️⃣ Download the Game Client

The game is available in three formats:

• EXE (Recommended for easy install): Automatically installs the game, sets it in the right folder, and creates a desktop shortcut.
• RAR or ZIP: Compressed formats. Require manual extraction before running the game.

Choose just one version to download. There’s no need to get all three.

We offer three mirror options for your convenience:

• 📁 Google Drive, 📁 Mega.nz, 📁 Files.fm

2️⃣ Installation Location

To avoid future errors, install the game in this folder:

C:\Games\MU

3️⃣ Running the Game

• Run the game using Launcher.exe.
• Make sure you have .NET Framework 3.5 installed – its required for the launcher to work.
• If Windows shows a warning about the developer, click "Run Anyway". This is expected since our developer certificate is personal.
• The launcher provides live updates so you never need to re-download the full client again.

4️⃣ Game Account

• You must register an account on our website.
• After registration, check your email and confirm your account activation.
• You can save your login and password in the launcher for quicker access next time.

✅ Trust & Safety

Our game files are safe. All warnings from Windows are related to missing corporate certification, but the files are secure and trusted by the project community.
