I have very slow internet, so I opted to just download the 28 files needed to play the game overnight.
Worked and installed great!
The forums stated at the time that the other/extra files were not needed as they were for the pre-release of the game.

Now there is a patch available?...
and now there is 29 files for the base game?...
and 3 or 4 more extra/other files than before?...
I submitted a ticket but haven't heard back and it's been over 5 days.

Forgive my ignorance as I do NOT understand the labeling of the files on gog.com (please see attached photo)
Please help as any advice or instructions would be greatly appreciated.

- Use Galaxy to update NEW and BIG games
or
- If you want to use offline patches for these kind of games: Check for new patches OFTEN; because you need ALL the intermediate patches and GOG deletes the older ones after a while.
Follow up on this forum and/or Larian's forum and/or gaming news sites.

In your case I would advise Galaxy updating or downloading+installing a new full offline installer every month or so. I can't help you with the offline patches if you don't or can't mention which version you've got installed right now.

Thank you for posting!!!
Attached is another screenshot of... the two versions?

The right one is the game version.
(left one is the Larian launcher version, I think - so irrelevant)

Your installed version is Hotfix 2.
The offline patches you now need are (listed in order):
patch_baldurs_gate_3_Release_-_v4.1.1.3630146_-_Patch_Patch0_Hotfix2_(66633)_to_Live_-_v4.1.1.3635601_-_Patch0 _Hotfix2.1_(66683)
patch_baldurs_gate_3_Live_-_v4.1.1.3635601_-_Patch0_Hotfix2.1_(66683)_to_Release_-_v4.1.1.3636828_-_Patch_Patc h0_Hotfix3_(66686)
patch_baldurs_gate_3_Release_-_v4.1.1.3636828_-_Patch_Patch0_Hotfix3_(66686)_to_Live_-_v4.1.1.3648072_-_Patch_ Patch0_Hotfix4_Launcher_fix_(66847)
patch_baldurs_gate_3_Live_-_v4.1.1.3648072_-_Patch_Patch0_Hotfix4_Launcher_fix_(66847)_to_Live_-_v4.1.1.366943 8_-_Patch_Patch1_Loca_fix_(67039)
patch_baldurs_gate_3_Live_-_v4.1.1.3669438_-_Patch_Patch1_Loca_fix_(67039)_to_Live_-_v4.1.1.3669438_-_Patch_Pa tch1_Data_fix_(67052)

So: HF2 -> HF2.1 > HF3 > HF4 > P1 > P1(datafix)

Thank you again for attempting to help me with this, I think I'm close to understanding.

It looks to me like you list five files for me to download and install in that order, but two of the five are not listed for downloading anymore? Is it safe to assume then that I need to uninstall, download every file!!!, reinstall the base game, and then the install the nine patch files in order based on the version number/s?

Thank you for taking the time to explain this and educate!!!
