Install both of them
completely, that means you choose "Custom" during the BG1 installation and check every component and you choose "Full" during the BG2 install.
Don't install them into their standard folders. Drop the
Program Files. Don't change the root directory names, though. I got my stuff in C:\BI\BGII - SoA and C:\BI\Baldur's Gate.
Once done, patch both of them:
BG1+TotSC patch,
BG2+ToB patch ( IF YOU HAVE THE GOG VERSION , SKIP PATCH BG1 )
Start a BG1 game, press Q for quicksave. Start a BG2 game, press Q for quicksave. Start a BG2:ToB game, press Q for quicksave.
Extract the
BiG World Setup into your
BGII - SoA folder.
Execute
BiG World Setup.vbs
On the next screen, you see three directories. Even if the first two already match with your installation folder, click the [...] besides them and navigate to the according directories. Why? If you installed and patched the games according to my instructions, the [...] will turn green. Green is good. Leave the third directory intact if you don't have a good reason not to.
