1. Both current GOG versions of BG1 and BG2 (setup_baldurs_gate_2.0.0.20.exe and setup_baldurs_gate2_2.0.0.12.exe) include and install "Aqrit's DDrawFix for Infinity Engine games". located at : http://bitpatch.com/ie_ddrawfix.html
Thus when you go to back up BWS complains that you already have a mod installed since it sees the "WeiDU.log" file in both "Baldur's Gate" and "BGII - SoA" folders. (Note if you want to install the BiG World Project or use BWS you need to rename the default BG2 installation folder to "BGII - SoA" when installating.) I just renamed the log file to "WeiDU-GOG-orig.log". The backup and additional scripts proceeded as normal without exiting. A copy of the file is below:
// Log of Currently Installed WeiDU Mods
// The top of the file is the 'oldest' mod
// ~TP2_File~ #language_number #component_number // [Subcomponent Name -> ] Component Name [ : Version]
~DDRAWFIX/DDRAWFIX.TP2~ #0 #0 // DDrawFix -> Force DirectDraw Emulation: v1.0
2. One other step I did before running the BWS, but that may not be necessary as the post was a year old, is the following per the link:

4. Make a folder \GOG Games\BGII - SoA\CD5\movies
5. Copy the file 25movies.bif from the folder \GOG Games\BGII - SoA\data\Movies to the new folder your just made.
6. Create a text file in Notepad named BG2-ToBPatchReadMe.txt in \GOG Games\BGII - SoA. This file can and should be blank inside, but it has to exist for a verification process the BiG World Setup does.
3. Change the download directory in BWS to a folder outside your BG folders as they will be deleted when you reinstall the games from the GOG setup files. That way you can keep a copy of the downloads Additionally you may not need to make backups since the GOG installs of the two files take only a few minutes. Probably just as fast as the restoration from the BWS.
Lastly, I am stuck in the extraction process for the "Standard BWS" install package since on e of the files is corrupted, but that's another post. BIG THANKS TO ALL THE MODDERS FOR ENHANCING THE BALDURS GATE SERIES! Ein herzliches Dankeschön! Merci! Doomo arigatoo gozaimasu!
