Improved Haer'Dalis' Swords > IntroductionBACK TO TOP


Improved Haer'Dalis' Swords is designed to work on the following Infinity Engine games:

  • Baldur's Gate II: Enhanced Edition (BG2EE).
  • The original Baldur's Gate II (BG2, or just SoA) with or without the Throne of Bhaal (ToB) expansion. Make sure you have Throne of Bhaal patched to version 26498. Check the ReadMe files related to your patch in your game folder and the BioWare website if necessary.
  • The conversion projects based on ToB, Baldur's Gate Trilogy (BGT) and Enhanced Edition Trilogy (EET).

This is a WeiDU mod, and therefore should be compatible with all WeiDU mods. However, we cannot test every single one. If you encounter any bugs, please report them on the forum!

Although it is not required for the Improved Haer'Dalis' Swords mod to function properly, classical game players are strongly recommended to download and install the latest version of the BG2 Fixpack before proceeding with the installation of this mod.

If you've previously installed the mod, remove it before extracting the new version. To do this, run  setup-swordap.exe , un-install all previously installed components and delete the 📁 swordap folder.

When installing or un-installing, do not close the DOS window by clicking on the X button! Instead, press the Enter key whenever instructed to do so.

Disable any antivirus or other memory-resident software before installing this or any other mod. Some (particularly avast and Norton!) have a tendency to report false positives with mod activity, resulting in failed installs.

You can extract files from the archive using 7zip, WinRAR, ZipGenius or another file compression utility that handles .zip files.

Special Note for Siege of Dragonspear from Steam/GOG

Good Old Games (GOG) and Steam both package the additional content for Siege of Dragonspear in a method that WeiDU, the tool used to install this mod, cannot access. You must run a program called DLC Merger on your SoD installation before you can install this or any other WeiDU-based mod.

Enhanced Editions Note

The Enhanced Editions are actively supported games. Please note that every patch update will wipe your current mod setup! If in the middle of a modded game you might want to delay the patch update (if possible) as even after reinstalling the mods, you might not be able to continue with your old savegames. Alternatively, copy the whole game's folder into a new one that can be modded and will stay untouched by game patches. It is important that you install the mod to the language version you are playing the game in. Otherwise, the dialogues of the mod will not show but give error messages.


Improved Haer'Dalis' Swords for Windows is distributed as an extractable compressed archive and includes a WeiDU installer.

Extract the contents of the mod to the folder of the game you wish to modify (the folder which contains the "CHITIN.KEY" file). On successful extraction, there should be a 📁 swordap folder and a setup-swordap.exe file in your game folder. To install, simply double-click  setup-swordap.exe  and follow the instructions on screen.

Run  setup-swordap.exe  in your game folder to reinstall, un-install or otherwise change components.

Mac OS X

Improved Haer'Dalis' Swords for Mac OS X distributed in the same compressed archive and includes a WeiDU installer.

First, extract the files from the archive into your game directory. On successful extraction, there should be a 📁 swordap folder, setup-swordap and setup-swordap.command files in your game folder. To install, double-click  setup-swordap.command  and follow the instructions on screen.

You can run  setup-swordap.command  in your game folder to reinstall, un-install or otherwise the components settings.


Improved Haer'Dalis' Swords for Linux is distributed in the same compressed archive and does not include a WeiDU installer.

Extract the contents of the mod to the folder of the game you wish to modify.

Download the latest Linux version of WeiDU and copy weidu and weinstall to /usr/bin. Then open a terminal and  cd  to your game installation directory.

Optional: run 'tolower' and answer 'Y' to both queries. You can avoid running the second option (linux.ini) if you've already ran it once in the same directory. To save time, the archive is already tolowered, so there's no need to run the first option (lowercasing file names) either, if you've extracted only this mod since the last time you lowercased file names. If unsure, running tolower and choosing both options is the safe bet.

Run  weinstall setup-swordap  in your game folder to install the mod. Then run  wine BGMain.exe  (or  wine baldur.exe  for EE games), and start playing.

Note for Complete Un-installation

In addition to the methods above for removing individual components, you can completely un-install the mod using  setup-swordap --uninstall  at the command line to remove all components without wading through prompts.
