You can choose your game type on the first screen of BWS. When you start BWS after the first time, it starts from the second screen, so click the Back button at the bottom to go back, then select "BGT customization" from the drop-down, followed by Next button.
Thanks. I've started a BWS install in debug mode and so far have encountered the following warnings/issues:
During the backup process the backup attempted to save the setup master (I ran this from the BG2-SOA install directory) and so the log file reported the backup failed.
Please wait a few minutes.

Please have a look at the log-file to resolve the problem.
As you can see, the backup worked, but because it tried to backup an open file (itself) it reported a failure. Does the BWS program have to be run from the BG2-SOA install directory?
Progressing on, I selected the "tactics" level installation so as to provide a reasonable test. I customised that installation with a few additions and removals to the various check boxes and resolved any conflicts and dependencies when choosing to continue. This process worked fine, so I proceeded to the download stage.
I had already downloaded many of the files I required and had them already extracted into the directory I had specified, but the program will only accept the packaged form of each mod - this isn't really a problem, but it might be nice to have this information stated in the initial screen so the user can be prepared. Anyway, most of the other files required for the install were successfully downloaded with these exceptions:
Animus: Sentient Weapon
Kari the Half-Kobold NPC (Beta)
Kiara-Zaiya NPCs
Wikaede One-Day NPC
Refinements
Baldur's Gate 2 Shadows of Amn Item Import
Houyi
Konalan's Tweaks
Lyric Bard
I managed to find working links to the Animus: Sentient Weapon mod and the Konalan's Tweaks mod. The other mods could not be found as all the links I was able to find were dead.
I proceeded onwards by removing those missing mods from the install as suggested, and the extraction phase started. The main part of that completed seamlessly, but I encountered a problem when the "further extractions" phase started because the setup had apparently not downloaded the "BiG World Fixpack". the "Big World Fixpack-Master" was downloaded, but perhaps you missed the "Big World Fixpack" from the list of included files?
Anyway I downloaded the missing file as suggested, and am proceeding with the install. I will let you know if any other issues arise.
