(by default it is “C:\Program Files (x86)\Steam\steamapps\content\app_377160”) in a separate depository folders. The Fallout 4 executable would be in a folder called “depot_377162”.
Next, create a new folder on your desktop, and copy the contents of each of the above folders into this new folder, replacing files as you go. Once finished, you have built the entirety of the previous version of Fallout 4: Game of the Year Edition. Congratulations!

How to install Fallout London manually or via mod admins
Now that you’ve downgraded Fallout 4 and downloaded Fallout: London via GOG, you can manually install the mod if you want to run it via mode manager program of your choice.
Start by locating where GOG downloaded the files. On my machine they are located at the following file path: This PC>SSD (E:)>GOG>Fallout London.
Here you will find the installer, F4SE, the Data folder and more. Remember that you will need to install Fallout 4 Script Extender (F4SE)done with either the F4SE files located in the installation directory or on the Silverlock website.
The next step is zipper the Data Folder and install the zip as a mod in your favorite mod manager: This PC > SSD (E:) > GOG > Fallout London > Data
It is strongly recommended to use the .ini files that are also included in GOG’s Fallout London mod. You can either replace the .inis in your Documents/My Games/Fallout 4 folder or you can add the .inis and their settings to your favorite mod managers ini editor. These ini files can be found in the _Configuration folderlocated at: This PC>SSD (E:)>GOG>Fallout London>_Config
