Run Multiple Accounts

Guild Wars only lets one client run per installation folder. To play several accounts at the same time, give each one its own copy of the game, then point an account at each copy.

1. Copy your Guild Wars installation

For every extra client you want running simultaneously, make a full copy of the game folder:

Copy C:\Program Files (x86)\Guild Wars\ to a new folder, e.g. Guild Wars (Copy 2), Guild Wars (Copy 3)…
Each copy must contain both Gw.exe and Gw.dat.

Once your copies are set up, GW Launcher can keep each one current — see Updating clients to pull the latest Gw.exe for every account at once.

2. Point one account at each copy

Add (or edit) an account per copy and set its Path to the Gw.exe inside that copy:

Add / Edit accountPath...

So account A → Guild Wars\Gw.exe, account B → Guild Wars (Copy 2)\Gw.exe, and so on.

3. Launch them

Double-click each account, or select several and use Launch Selected:

Select accountsLaunch Selected

Each client runs from its own folder, and the Active column shows which accounts are currently in. The launcher renames each window to its character/title so you can tell them apart.

Notes

Each copy keeps its own settings, screenshots, and GWToolbox/plugin folder. They start as a clone of the original but diverge from then on.
Running many clients is CPU/RAM heavy — that’s a hardware limit, not a launcher one.
Per-installation plugins live in <that copy>\plugins\; see DLL Plugins.
