This setup guide walks you through a safe WoW 3.3.5a client install using the RealmRanking direct download mirror. The process is straightforward—easy installation with no bundled adware.
1. Download the client
Grab the verified 3.3.5.12340 archive from the WoW 3.3.5a client download page. Extract it to a folder such as C:\Games\WoW-335a.
2. Configure realmlist.wtf
Open Data\enUS\realmlist.wtf (or your locale folder) and set set realmlist to your private server's address—for example set realmlist logon.yourrealm.com.
3. Launch and patch
Run WoW.exe. If your server supplies a custom launcher or MPQ patch, apply it before logging in. Disable Windows Defender exclusions only for the game folder if false positives appear—our mirror is scanned, but heuristic tools may flag older executables.
