Installing & launching

The Eden launcher is a small program that downloads the full game (about 58 GB), keeps it updated and starts it. You never patch anything by hand. Follow the steps in order: step 3 (antivirus) is the one most new players skip, and it's the reason most installs fail.

What you need#

• Windows 10 or 11, 64-bit
• About 65 GB of free disk space
• About 20 minutes of clicking, plus the download time (it depends on your internet: roughly 1-2 hours at 100 Mbps)

Step 1: Make an account#

Go to the Play page and create your Eden account. Remember the username and password: you sign in to the launcher with them, not with an email.

Step 2: Make a folder for Eden#

Create a new, empty folder, for example C:\Games\Eden.

• Don't use Program Files, Desktop, Downloads or a OneDrive folder. Windows and OneDrive interfere with programs writing their own files there.
• Pick a drive with 65 GB free. Any drive works (D:\Games\Eden is fine).

Step 3: Tell your antivirus to leave that folder alone#

Do this before you download anything. Antivirus programs often flag private server launchers (they aren't code-signed and they patch the game) and silently delete game files. That's what causes "files not found", "can't proceed" and "the launcher disappeared".

Windows Security (Windows Defender), which most PCs use:

1. Press the Start button, type Windows Security and open it.
2. Click Virus & threat protection.
3. Under Virus & threat protection settings, click Manage settings.
4. Scroll down to Exclusions and click Add or remove exclusions. Click Yes if Windows asks.
5. Click Add an exclusion → Folder, and pick your Eden folder (C:\Games\Eden).

That's it. Windows Security keeps protecting the rest of your PC.

Other antivirus programs have the same option:

If yours isn't listed, search its settings for exclusions, exceptions or allow list.

Step 4: Download the launcher#

1. Download Eden Launcher.exe from the Play page. Only download it from edenmaple.net.
2. Your browser may warn you: - Chrome: "This file isn't commonly downloaded". Click Keep (or open the downloads list and choose Keep). - Edge: "... isn't commonly downloaded". Click ⋯ → Keep → Show more → Keep anyway. - Firefox: click the download arrow and Allow download.
3. Move Eden Launcher.exe into your Eden folder. Keep the file name: the launcher uses it to update itself.

Step 5: Open the launcher#

1. Double-click Eden Launcher.exe.
2. If Windows says "Windows protected your PC", click More info, then Run anyway.
3. If Windows asks "Do you want to allow this app to make changes to your device?", click Yes. The launcher needs it to install and protect the game.

Step 6: Install the game#

1. The launcher shows the install folder. It should be your Eden folder. If not, click Choose folder... and pick it.
2. Click DOWNLOAD & INSTALL.
3. Wait for it to finish. You can click Pause or close the launcher, and it continues where it stopped next time.

Step 7: Sign in and play#

1. Sign in with your Eden username and password from step 1.
2. Click Play. The launcher checks for updates and your game files, then starts the game.
3. The first start takes a few minutes while the game loads its data. The screen can look frozen. Give it time.
4. In game, pick a world and channel, create a character, and you're in. New to MapleStory? Read Never played before? next.

"Files not found" or "can't proceed"#

Your antivirus removed something. Fix it in this order:

1. Add the exclusion from step 3 if you skipped it.
2. Get the deleted file back: Windows Security → Virus & threat protection → Protection history. Click each Eden entry → Actions → Allow on device (or Restore).
3. Open the launcher, sign in, and click Verify game files (the small link under Logout). It checks every file and downloads whatever is missing.
4. Click Play again.

If the launcher itself disappeared, restore it from Protection history the same way, or download it again from the Play page after adding the exclusion.

Updates#

The launcher checks for updates every time you open it. It updates itself and the game automatically, so always start Eden through the launcher.

The launcher also runs Eden Anticheat. When you press Play it checks your game files and repairs changed ones, and while you play it watches for cheat tools. The server only lets you play while it runs, so starting MapleStory.exe directly won't keep you in game. See Troubleshooting if it closes your game.

The launcher and your connection#

When you press Play, the launcher sets up a local connection to the Eden server. Usually this is automatic and you can close the launcher afterwards. If the launcher says to keep it open, leave it running while you play. Closing it would disconnect you.
