Get into the realm

You keep the World of Warcraft 3.3.5a you already have. The launcher adds the realm's files to it, sets the address, and starts the game. There is no second 4 GB client to download.

Two things to know before you run it

Unzip both files into the same folder. The zip holds HasteLauncher.exe and config.json, and the launcher needs the second one sitting next to it to know where the realm's files are. If you double-click the .exe from inside the zip window, Windows copies only the .exe somewhere temporary and the launcher will tell you it cannot find the patch files.

Windows will warn you. The launcher is not code-signed, so SmartScreen shows a blue "Windows protected your PC" box. Choose More info then Run anyway. That warning is about the missing signature, not about anything it found — but you only have our word for that, which is why the SHA-256 is printed above and the manual route below does the same job with no .exe at all.

  1. Unzip it

    Right-click the zip, Extract All, and pick any folder you like — Downloads is fine. Keep HasteLauncher.exe and config.json together.

  2. Run HasteLauncher.exe

    Click through the SmartScreen warning as described above. The launcher opens a single small window.

  3. Point it at your WoW folder

    The folder that contains Wow.exe. It usually finds it on its own; if it does not, browse to it. It checks the folder really is 3.3.5a build 12340 before it touches anything.

  4. Let it install

    About 400 MB of realm files, resumable if your connection drops. It also changes five bytes in Wow.exe so the client will load the realm's interface files — the stock client signature-checks them and refuses to start otherwise. Your original is kept as Wow.exe.backup-preHaste, the launcher shows you the exact byte difference before it does it, and it can undo the whole install later.

  5. Log in

    Use the account name and password you chose when you registered. Do not have one yet? It takes a minute: create an account.

What you need

The game
An existing World of Warcraft 3.3.5a (build 12340) install. Any language. The launcher will not touch a Cataclysm or later folder.
Disk space
About 500 MB free in the WoW folder.
Operating system
Windows. There is no macOS or Linux build; the launcher runs under Wine for people who already do that, but it is not tested there.
Realm address
set realmlist 38.247.161.169

Rather not run an unsigned .exe?

Reasonable. Everything the launcher does can be done by hand, and the files it fetches are plain downloads you can inspect first.

  1. Copy the patch archives into your Data folder

    Download these three and drop them in <your WoW folder>\Data\:

    patch-C.MPQ · patch-H.MPQ · patch-S.MPQ

    The file list, sizes and SHA-256 for every one of them is in manifest.json.

  2. Set the realm address

    Open <your WoW folder>\realmlist.wtf in Notepad, delete everything in it and put this single line in:

    set realmlist 38.247.161.169

  3. Patch Wow.exe

    This is the one step that is genuinely awkward by hand: five specific bytes have to change or the client refuses to start with "login interface files are corrupt". The exact offsets and before/after bytes are published in manifest.json under exe_patch, so you can make the edit in any hex editor and verify it against what is written there.

Those file links are served from the realm's own patch host over plain HTTP, so your browser may warn about leaving a secure page. The archives are checksummed in the manifest either way — that is what proves they arrived intact, not the transport.

If something goes wrong

Open a Command Prompt in the folder you unzipped to and run:

HasteLauncher.exe --selfcheck report.json

It writes a small text file saying whether it can reach the realm, whether your game folder is a real 3.3.5a client, and whether Wow.exe has been patched. Post that in the Discord and it is usually a one-line answer.

The launcher never asks for your account password. Nothing on this page does — only the game client and the login page on this domain ever should.
