Solution to make fallout london run

[Deadly Designer]

Mine is GOG version but if yofollow the install instructions for Steam it will fix the crashes:

I follow this:

BUFFOUT 4 INSTALLATION - INSTALL THESE FILES MANUALLY

1. Download the Buffout 4 Main File on NEXUS: https://www.nexusmods.com/fallout4/mods/47359

and extract the archive somewhere on your PC.

2. Place / move the extracted F4SE folder into your Fallout 4/Data or Fallout 4 Data folder (& overwrite if asked).

And:

inside the buffout 4 zip is a folder called F4SE. If you go into your fallout 4 install folder -> data folder, you’ll see another folder called F4SE. Overwrite that with the one you just downloaded. It will insert the files you downloaded to the fallout folder without deleting existing ones.

Finally:

Go into the fallout 4 folder. There is a f4se_loader (fallout 4 script extender) .exe. I created a shortcut to it on the desktop, went to compatibility mode and chose to run as administrator. Renamed it to Fallout 4 London because I like to know what I’m looking at. Launch the game through this instead.

JUST REMEMBER! If you've got a Nvidia videocard, turn of weapon debris (fallout e ini or fallout 4 launcher option).
It's been crashing the game for years and Bethesda/Nvidia haven't acknowledged it at all.
