Fallout London requires Vault 13 Demo requires Fallout 4 Next Gen is


Read-Only

For Steam users, to stop Fallout 4 from auto updating to the latest version:

  • Find "appmanifest_377160.acf" and set it to Read-Only
    • I have two copies of the .acf, one each with the flag set differently

Clean Base Installs

Note: make sure you local saved games are safely backed up. I'm not sure I'll look too hard in how to manage saved games (maybe there is a mod for that).

1.10.163.0

  • Goal: Create a clean installation folder named "Fallout 4 - 1.10.163.0"
  • Pre-Requisite: .....\Steam\steamapps\appmanifest_377160.acf is set to Read-Only
    • See notes above
  • Background: Since the Nextgen update there have been mods coming out that require the pre-Nextgen Fallout installation to work. Creating a clean base install folder that can be used as the foundation for starting different mod installs seems like the way to go. G

1.10.984.0

  • Make sure that the current Fallout 4 isn't really needed.
  • From the library manager, remove the installation.
  • Start a fresh installation.
  • After install, before you run the game, copy the Fallout 4 folder
  • Rename the copied folder "Fallout 4 - 1.10.984.0"
  • Place the new folder at ...Steam\steamapps\common

Clean Base Install Prep

You should now have a copy of each Fallout 4 base version, never run, at ...Steam\steamapps\common. Next steps will make copies of these folders in relation to the specific mod.
