I have tried installing the BWP over 10 times now. No matter which step by step instructions I follow It always stalls at this screen. Hitting any key to continue just brings the screen up again, an endless loop.

Which set of instructions are the most up to date for installing the BWP with gog.com's version of BG1&2?

Am I missing something?

The most frustrating thing is that I can get this working with my disc set but not GoG's.

Have you read this thread, especially the GOG specific tips in post # 3 ?

Thank you for the attempt. Yes, I have done this, but to no avail. I should also point out that it works fine if I only want to mod BG2 and not BG1. SOMETHING is making it stall when trying to install those mods. I cannot for the life of me figure it out.

Yeah, I hit that problem too on one of my many failed attempts to install Big World. I decided to ditch it and go with a smaller handful of individually installed mods instead, but I hope you find the answer. :)

I will attempt this and get back to you. What do you mean by control the process though? Does it just go out of control without that check or something?

Ah, I see. Yes, your first post solved the issue. I also highlighted the above post as a solution because it may apply to someone else, but I did not need to find these. The downloader found them just fine for me.

The proposed solution while maintaining the same checking did not work for me:

ADDING:

%GOG% %IFN% %BG1%readme_patch.txt" GOTO :BG1CHCK2

AFTER:

%NGOG% %IF% %BG1%readme_patch.txt" GOTO :BG1CHCK2

However, the workaround did:

REMOVE:

GOTO :TP1CHECK

All this is to be done before BiG World Install.bat is started.

This can be done by editing BiG World Install.bat with notepad or a similar editing tool, such as Notepad++.

Yes, the removal of GOTO :TP1CHECK was in post #10 that I mentioned. That's why it's not a proper solution but a workaround.

It's good the downloader found those files automatically, for me I had to download and extract them in BG2 folder.

Unfortunately I can't give you any insight for the rest of the process since I didn't pay any attention whatsoever after that part. I would be interested to know your result.

I had the same problem and solved it in a similar way (I simply added the line "%GOG% GOTO :BG1CHCK2" right under the marker ":TP1CHECK", which marks the begin of the looping section. The effect is the same as in the solution proposed above, the looping sequence is simply bypassed.

There's no harm in this, because (as far as I can tell) the looping sequence is just meant to ensure that the game (Baldur's Gate 1) is properly patched. The GoG installation _is_ properly patched (unless someone tried to manually install another patch over it, which isn't recommended), so the test is unnecessary in this case. There's probably a more elegant solution to the problem, but I didn't bother decoding all the conditions in the lines below my change, I was happy that I found a solution.

With this change, the BiG World installed worked flawlessly. It was actually fun to watch the part when it opens/closes lots of windows and extracts all the mods, even exe files packed inside other exe files. That's quite impressive.

Side note (unrelated to your problem, but worth a mention anyway imho): I think it's really important to disable UAC and shut down antivirus and firewall programs, as recommended in the documentation. In my first attempt to install BiG World, I didn't do that, and it caused lots of problems. My firewall prevented some scripts from executing other files, I then had to extract some mods manually, but apparently didn't do it correctly, and in the end I borked the whole installation. Good thing I had made a full backup. After switching off UAC, fireall, and antivirus, everything worked.

I would like to add that I had the same issues. I didn't turn off UAC, but I ran cmd.exe as administrator and launched the Big World Setup.vbs directly from there instead.
