Step 1. Download the client
Step 2. Choose the install folder
Step 3. Unpack the archive
Step 4. Set the realmlist
Step 5. Create a shortcut and set compatibility
Step 6. First launch

Step 1. Download the client

Get the full Vanilla 1.12.1 client (about 5–6 GB) any way you like — see download WoW Vanilla or download via torrent. Wait for the download to fully finish, or the archive won't unpack.

Step 2. Choose the install folder

This is the step where newcomers most often make mistakes.

Install into a short path with only Latin letters, no spaces: for example C:\Games\WoW.
Do not install into C:\Program Files or Program Files (x86) — Windows restricts writing there, so the client cannot save realmlist.wtf, settings and addons.
Keep at least 8 GB free on the disk (archive + unpacked files). See how much the client weighs.

Step 3. Unpack the archive

Unpack the downloaded archive (.zip, .rar or .7z) into the chosen folder with 7-Zip or WinRAR. Afterwards the folder should contain Wow.exe, the Data, Interface, WTF folders and the realmlist.wtf file.

Step 4. Set the realmlist

Open realmlist.wtf in Notepad, delete everything and write one line:

set realmlist play.wowx5.ru

Save the file. Common mistakes (an extra .txt extension, a read-only attribute, the wrong locale folder) are covered in the set realmlist guide.

Step 5. Create a shortcut and set compatibility

Right-click Wow.exe → Send to → Desktop (create shortcut).
If the game won't start or crashes on Windows 11 — right-click Wow.exe → Properties → Compatibility → enable Windows XP (SP3) compatibility mode and Run as administrator.
See Windows 11 compatibility for details.

Step 6. First launch

Launch via the shortcut, enter your X5 login and password, and pick the realm. No account yet? Register. If the client can't see the server, check unable to connect fix.

Done! Next up: connecting to the server and your first steps in Azeroth.

FAQ

Do I need to run an installer for WoW 1.12.1?

Usually no. The Vanilla client ships as an archive — just unpack it into a folder. No installer is required; the game runs from Wow.exe.

Where should I install the client?

In a short path without spaces or non-Latin characters, for example C:\Games\WoW. Do not install into Program Files — permissions may prevent saving settings and realmlist.

Do I need compatibility mode on Windows 11?

Often not, but if the game won't launch or crashes, enable Windows XP SP3 compatibility and Run as administrator for Wow.exe.
