Multi-Install Tool

A Gibberlings Three Mod
Author: andrewas, Orion's Stardom

Version 5.1.10 - Check for the most recent version


The multi-install tool is a program which allows side-by-side installs of Baldur's Gate II at a minimal size. This can be useful for example when playing incompatible mods, or when wanting to test a mod on a fresh install. Specifically, it follows the instructions posted by igi in Discussion: Multiple BG2 Installations.


To use the multi-install tool, you will need:

Supported Infinity Engine Games

The Multi Install Tool will work on any of the following Infinity Engine games:

Note: Mac OS 9 games are not supported.

In general, any patches or mods after the official patches for each game will have no impact on support by the Multi Install Tool.

Usage Instructions

  1. Ensure that you have met the requirements above.
  2. Download and run the multi-install tool.
  3. Fill in the fields as follows:
    • Source: an existing BG2 installation, to be used as a basis for the clone.
    • Sink: where you want the new installation to live on your disk.
  4. Optionally, change any available preferences in the lower pane. Depending on the game you have selected to clone, your operating system, and whether you have any save games, not all of the displayed options will be enabled. Each option will increase the size of the clone directory, but may be required for certain functionality or mods.
    Note: if 'data' is selected, 'music' will always be copied, regardless of whether that checkbox is selected.
  5. Click 'Go'.
  6. Wait until the progress bar fills in and says 'Done'.
  7. Run the clone with the main executable (eg, 'bgmain.exe' - not baldur.exe) in the clone folder.

The newly-created install will have the same set of patches and mods to start with as the one it was cloned from. You can apply mods as usual to the cloned game, and they will not affect any other installation you have on your system.

Command-Line Options

The Multi-Install Tool supports the following command-line options, useful for batch-mode operations and for launching the Multi Install Tool from another application with pre-filled default values.

Multi-Install Tool command-line options
Select a folder to use as a source game.
Select a destination folder for the clone.
If provided, do not launch the GUI, and operate in batch mode. Otherwise operate interactively.
If given, duplicate the entire contents of the 'data' folder, the 'music' folder, and the 'movies' folder, if they exist. Also change the value of hd0: in the ini file to point to the sink, rather than patching the main executable.
Otherwise, create a data folder in the sink directory filled with nonsense data (so that mods checking for the existance of an expansion pack will work properly).
If given, duplicate the entire contents of the 'music' folder, if it exists. Otherwise, create a cloned game which reads this information from the original game.
Note: This preference is implicitly given by giving '--copy-data'.
If given, duplicate the entire contents of the 'characters' folder, if it exists. Otherwise, create a cloned game without this data.
If true, duplicated any save games that exist. Otherwise, create a clone game with no saved games.
If true, duplicate the entire contents of the 'portraits' folder, if it exists. Otherwise, create a clone without this information.
-v, --verbose
If given, print everything that's happening to STDOUT. Otherwise, be quiet unless something goes wrong.

Not all --copy-* options are meaningful on all configurations. In particular, if the Multi-Install tool detects that it can use symbolic links, then only --copy-save has any effect.
