1. Fully install Baldur's Gate: The Original Saga
2. Fully install Baldur's Gate II Complete.
3. Download
Baldur's Gate II Fixpack (Download links are on the left side) and extract it to your Baldur's Gate II directory.
4. Run the newly extracted setup-bg2fixpack.exe (if not automatically started).
5. It is safe to select yes for all the optional fixes, but if you want to learn about each in detail, consult the readme file that comes with the fixpack.
6. Download
BGT-WeiDU and extract it in your Baldur's Gate II directory.
7. Run the newly extracted Setup-BGT.exe and follow the instructions. You may need to run it in administrative mode in Windows Vista/7.
8. Enter Baldur's Gate I's directory when asked (if not already provided)
9. Wait for BGT-WeiDU to finish installing.
10. OPTIONAL: Download and install
Baldur's Gate 1 Unfinished Business as well as
BG 2 Unfinished Business. These mods restore things that were previously cut from the released product, so while you don't need them, and they do add new content, they're pretty nice to have, especially if this is not your first time.
11. OPTIONAL: Download and install any user-created material (banter packs, expansion mods, new NPCs, etc.)
12. Go to your Baldur's Gate II directory, then find and run the file Setup-BGTMusic.exe and select 'Hybrid Baldur’s Gate/Shadows of Amn/Throne of Bhaal music'. This makes it possible to hear the original Baldur's Gate music when playing Baldur's Gate I.
13. OPTIONAL: (for more experienced users) Download
Baldur's Gate II Tweak Pack and apply it in the same way as the fixpack. Consult the readme file for details of each tweak - too many to list here. If you don't know what a tweak does even after consulting the readme, just skip it.
14. Download the
widescreen mod and apply it in the same manner as the fixpack. This makes it possible to play the game in high resolutions and in widescreen format.
15. Remove the Baldur's Gate I installation if you wish - it's done its job!
