Fallout 4

Re-installation and configuration of the vanilla game.

Installation directory

In order to ensure that your Fallout 4 installation is pristine and vanilla, we are going to completely re-install the game. This is especially important if you have modded the game previously as left-over files might interfere with your WTP installation.

UAC protected folders

The reinstallation also serves the purpose of relocating the game files to a better directory. Using UAC protected folders (such as C:\Program Files or C:\Program Files x86) for the game or any modding tools has a risk of causing issues down the line. It is best to avoid those folders to begin with. Most Wabbajack list authors, myself included, will not provide support for people that disregard this warning and use UAC protected folders anyway.

Note that this does not include the Steam client. Most people will have it installed under C:\Program Files x86\Steam which is completely fine.

Fallout 4 and Mod Organizer 2 should be installed on the same hard drive. Ideally that hard drive would be an SSD to reduce loading times and eliminate stuttering.

Uninstallation

If you never modded Fallout 4 and never installed other Wabbajack lists, you may skip this step. However, I still recommend you verify the game files through Steam in that case.

  • Uninstall Fallout 4 through Steam
  • Navigate to your Fallout 4 directory: C:\Program File x86\Steam\steamapps\common\Fallout 4.
  • Delete any left-over files in this folder.

INI Folder

More Fallout-related files are located inside the so-called INI Folder which needs to be cleaned out as well. It contains your savegames as well as the game’s INI files and, if you modded Fallout 4 before, F4SE plugin logs.

  • Navigate to the INI Folder:
    • C:\Users\{Your User Name}\Documents\My Games\Fallout4
  • If you have an ongoing vanilla playthrough, back up the Saves folder.
  • Delete everything inside the Fallout4 folder.

You can simply move the Saves folder to Fallout 4 Modding\Backups.

Reinstallation

In order to prevent some confusion, I will refer to the Library in Steam as the Game Library. It is the second of four items in the top menu in the Steam client and contains a list of all your games.

A Steam Library on the other hand is a folder on your hard drive into which Steam games are installed. By default this would be C:\Program Files x86\Steam\steamapps\common\. Since we do not want to have files inside a UAC protected folder like Program Files x86, we should not install Fallout 4 in the default directory. A new Steam Library is required.

Unfortunately Steam allows only one Steam Library per hard drive. You can find a workaround here.

Creating a new library

If you already have a separate Steam Library outside the UAC protected folders on the drive you want to install Fallout 4 and Mod Organizer 2 on, skip ahead to the next step.

Otherwise follow the instructions below to create a new Steam Library:

  • Open Steam and go into the Settings.
  • In the Downloads tab, select Steam Library Folders.
  • Click Add Library Folder.
  • Point it to a location somewhere outside the UAC protected folders, e.g. G:\Steam Library\.
  • Close all windows when you’re done.

Setting the language to English

Non-English installations of Fallout 4 are not supported.

  • Right-click Fallout 4 in your Steam games library.
  • Select Properties and switch to the Langauge tab.
  • Ensure that the language is set to English.

Reinstalling the game

  • Open Steam and go into your Game Library.
  • Find Fallout 4 in the list and click Install.
  • As location, select a Steam Library in a non-UAC protected folder and click Next.

Wait for Fallout 4 to be downloaded before you proceed.

Regenerating INI Files

After re-installing the game, it is important to launch it at least once through Steam so that the registry keys are set up. Otherwise, certain modding tools may not recognise the game. Upon launching the game, the default set of INI files will also be regenerated.

  • Find Fallout 4 in your Games Library and hit Play.
  • You will be prompted with a notification that Fallout 4 is configuring your video options, click OK.
  • Click OK again to the next window and hit Exit to close the launcher.

Regenerate INIs

Future Updates

The most important mod for most Bethesda games is the Script Extender, a resource that is in turn required for many key mods. The Fallout 4 Script Extender (F4SE) is version dependent. It requires a specific version of Fallout 4. For instance, F4SE 0.6.21 requires Fallout 4 1.10.163, and will not work with any other version of the game.

Unfortunately any update for the Creation Club requires the game executables to be updated which breaks F4SE every time. When that happens, the Script Extender team usually updates F4SE within a few days. Any F4SE plugins will have to be updated by their respective authors as well which can take several weeks.

In order to prevent Creation Club updates from interrupting your playthrough and breaking your game, we are going to disable automatic updates in Steam. We are also going to backup the current version’s executables so you can restore them at any time.

Disable Auto Updates

  • Open Steam and find Fallout 4 in your Game Library.
  • Right-click it and select Properties
  • In the Updates tab, change Automatic updates to Only update this game when I launch it.
  • Close the Properties window.

Steam Disable Auto Updates

Executables Backup

Although Steam will no longer update Fallout 4 automatically, I still recommend keeping backups of the two executables (Fallout4.exe and Fallout4Launcher.exe), just in case. If you accidentally updated, all you need to do to roll back is replace the executables in your root folder with the ones you backed up. This also comes in handy if you had to regenerate INI files or validate game files through Steam for whatever reason and were forced to update.

  • Navigate to your root folder: Steam\steamapps\common\Fallout4.
  • Copy (CTRL + C) Fallout4.exe and Fallout4Launcher.exe.
  • Paste (CTRL + V) them to Fallout 4 Modding\Backups\Executables 1.10.163.0.

Official High Resolution Texture Pack

Bethesda published a free 55GB texture pack with upscaled 4K textures that are nowhere near worth the hard drive space, especially not when compared to higher quality mod-added textures. If you had the HD DLC installed previously, you need to disable it in Steam.

  • Open Steam and go into your Game Library.
  • Go to the Fallout 4 page and click Manage my 8 DLC.
  • Uncheck Fallout 4 - High Resolution Texture Pack in the list and click Save.

Disable HD DLC

Creation Club Content

If you bought any “creations” from the Creation Club (or grabbed some while they were available for free), they may still be present in your Data folder. Some select “creations” are supported in WTP as of version 1.6 but I recommend you install them as separate mods later on.

  • Navigate to steamapps\common\Fallout4\Data and cut (CTRL + X) all files starting with cc.
  • Paste (CTRL + V) all files to Fallout 4 Modding\Backups\Creation Club.
