How To Mod Fallout 4 Pc Nexus
Dec 06, 2016 Like many Bethesda games, modding is one of the big draws of games like Skyrim and Fallout 4 on the PC. Nexus Mod Manager is one of the best ways to install mods on your favorite games, and we’re here to show you how to use it.
This Tutorial aimed to be simple by leaving out all the information you don't need and to get an overview. If you use Windows Vista or Windows 7, you should read Point V) Installing Fallout first.
More information and further Links you'll find at the end of the article.

Must Haves
- a 'Data Compression Utility' like 7zip, WinRAR, IZArc or TUGZip -> to extract file archives
- Nexus Mod Manager (NMM) -> The official Mod Manager. Currently in beta stage and regarding tools not as powerful as FOMM, but more features will follow
- Fallout Mod Manager (FOMM) -> optional Fallout Launcher providing very useful Modding-Tool, like BSA browser, BSA creator and TESsnip
- Fallout Script Extender (FOSE) -> many Mods require its additional scripting commands to work
Recommended Additions
- FO3Edit -> detects Conflicts between Mods, a powerful tool for Mod editing
- Better Oblivion Sorting Software for Fallout3 (BOSS for FO3) -> sorts your load order automatically
- Fallout Mod Sorter (FOMS) -> another load order helper
- ArchiveInvalidation Invalidated -> does the whole 'ArchiveInvalidation'
- Games for Windows LIVE Disabler -> disables GfWL and moves your DLCs into your game folder
- Fallout Installation Cleaner (FOIC) -> cleans up your Fallout; removes Mods, 3rd party tools, ... etc
Mods come as package -> first you need to extract them to a temporary location by using a tool like 7zip. Examine the files / folders of the Mod you've unpacked to get a quick overview.
Example of an unzipped Mod under XP and Vista / Windows7
You'll find files with ending *.esp or *.esm and maybe additional folders like textures, meshes or sound.
After you unpacked a lot of Mods, you'll consider each result as quite unique, but generally the structure is almost the same.
Anyway, there are two common rules you should keep in mind:
- All Mods have to be placed into the Data Directory of your Game.
- The folder structure must be correct.
The Data Folder
-> The default path for DVD Versions is C: Program Files Bethesda Softworks Fallout 3 Data
You may have customised the install path to something else e.g. C: Games Fallout...
That's why in some READMEs you'll find the term '< install path > Fallout 3 Data '
-> The default path for Steam Versions is C: Program Files Steam steamapps Common Fallout 3 Data
To avoid issues under Vista and Win7, the install location of Steam can be customised, see point #V .29 Installing Fallout
The Folder Structure
Files that belong into the. This is the process to recognise certain new files which have been placed into the Data folder.How To Mod Fallout 4 Pc Nexus Mod
-> It's recommended to use the little tool ArchiveInvalidation Invalidated.
-> Unzip, run it, activate it
The whole Archive Invalidation will be done.
Finally check your G.E.C.K. Mods (*.esp) at your Fallout Launcher or use FOMM

Mods are best installed by your own.
( Avoid extracting something directly into your Game / Data Dir )
- There could be a ReadMe -> It‘s recommended to read it before you install a Mod
- Make a save game that is 'clean'. -> You could need it later - just to be sure
- If you install a Mod by your own, you‘ll know how to remove it
- Only add one Mod by one. -> Test it. -> If you install a plenty of Mods, you‘ll probably have to spend a plenty of time to figure out, why your game is crashing.
- Take care of Mod Conflicts and your Load Order. Tools like FO3Edit and the Fallout Mod Sorter (FOMS) help to increase your games stability.
- If something went terribly wrong, you'll be lucky if you backed up your Data folder
Keep your System up to date.
Perform a Windows Update including DirectX.
Clean your Windows
(CCleaner recommended) and reboot.
Install Fallout.
If you use Windows7 or Vista, it is highly recommended to install the game to another location than 'Program Files' ( for example C: GamesFallout 3 ) to avoid problems with the security feature UAC.
Alternatively you could disable UAC, but this may lead to a less secure system, so be warned. For Steam versions there is hardly a way to customise the install dir. So you may need to go for the 'disabling UAC' option - or install Steam to another location than 'Program Files'
e.g. C:GamesSteam ....

Install the latest official Patch
Install the latest official Patch which fits to your game version. Note, that Steam and GotY versions should already be up-to-date.
=> If you get the xlive.dll error at start, see solution here: Games for Windows Live fix.
Backup your 'clean' Data folder before installing Mods.
It saves time if something went wrong - especially if you installed Fallout via Steam.
( a reinstall wont work in every case properly.

- Backup save games and your ArchiveInvalidation.txt file if you use one
- Uninstall Fallout3 in your System Control (Software / Programs) or use a helper like the Revo Uninstaller
- There are two Folders left: the Game Dir (with your Mods) & your 'My Games' folder
- -> delete or simply rename the Folders to backup
- -> be careful with backed up data and avoid using old *.ini files
- Clean Registry (CCleaner)
- Reboot your System, to get all Registry changes applied
- Go on with Point V) Installing Fallout
You can play Fallout in two different ways: off-line or on-line via GfWL.
As soon as you switch between these two modes, if you install F.O.S.E. (which disables GfWL) or if you simply move your DLC files into the Data folder, you'll consider your save games are 'gone'. This happens because Fallout uses two slightly different locations to store the game saves in.
- off-line: <Start Menu> Documents My Games Fallout3 Saves
- on-line: <Start Manu> Documents My Games Fallout3 Saves 'Your Live Name'
-> If you want to continue your game on-line or off-line, simply copy the save games into the respective location.
Sometimes you need to access hidden folders on your Hard Drive.
For example if you want to access the GfWL Folder where DLCs are stored in.
- XP: C: Documents and Settings 'User Account'Local SettingsApplication Data Microsoft Xlive
- Vista: C: Users 'User Account'AppData Local Microsoft XLive
These Folders are hidden by default so you may need to set them visible.
If you have to deal with several file extensions like *.exe, *.esp or *.bsa, you should disable Hidden file extensions too.
- Open a Window, e.g. 'Computer' ( on Win7: hit < Alt > if the menu bar wont be shown on top of the window )
- Go to Tools --> Folder Options and click the View tab.
- In the Advanced settings list, enable the point 'Show hidden files and folders'.
- Click to clear the check box 'Hide extensions for known file types'.
- Apply this setting, and click OK.
If you test a lot of mods you may want to have quick and easy access to your data folder.
Creating a Desktop Shortcut:
- Go to your Fallout 3 folder ( by default C:Program FilesBethesda SoftworksFallout 3
- or on Steam versions C:Program FilesSteamsteamappsCommonFallout 3 )
- Right-Click on the Data folder icon
- go to 'Send to'
- click on 'Desktop (create shortcut)'

Sometimes it is recommended to use the Fake Patch and the Unofficial Fallout 3 Patch as workaround if you don't want to use the official Patches. But keep in mind that this wont work in every case properly. The latest official patch (v1.7) should be your very first choice.
Sometimes Modders get their file structures not correct.
In this case you could try to correct this by your own.
Use a tool like FO3 Archive Utility (requires Java) or FOMMs built in BSA Browser to open the *.bsa archives (e.g. Fallout - Textures.bsa) to get an idea, how the folder structure has to look like.
But do not try to change the *.bsa Archives!

Here you reached the end ;-) and hope it helped to clear some things up.
Enjoy Fallout3Nexus and don`t forget to rate and comment a tested mod. Keep in mind it is lots of hard and unpaid work.
... happy modding folks

Fallout 4 allows you to take on an American life after nuclear fallout, but instead of rescuing people, forming settlements, putting the Minutemen back together and finding your son, why not customize the experience to suit your needs? There are thousands of mods available for Bethesda's title and many of them share similar qualities to Skyrim counterparts.
We rounded up some of the best to get you started.
Another Life
Similar to how Alternative Life works in Skyrim, with this mod installed you regain control of your destiny ... or rather how it begins. You will be able to select from 36 different occupations, each dictating starting gear, faction relations, and more.
Armor and Weapon Keywords Community Resource (AWKCR)
Aside from the horrifically long name, this incredible mod allows for other mods to work some magic with a standardized framework for armor and weapons. Not only that but crafting menus, color and decals and slot usage are all affected, to help prevent conflicts. If you wish to add some more stuff for your character to use, you need this mod.
Armorsmith Extended
After installing AWKCR, you'll want to pick up Armorsmith Extended. This is a huge mod that does a bunch of things. It can allow for shirts and other wearables to be worn under armor — because who wears plated armor on the skin? — and even make it possible to wear bandannas and other accessories while rocking a helmet.
Other cool features include the ability to rename clothing and craft more item types.
Venturing out into the wasteland with only the companions Bethesda deems acceptable isn't much fun. There are a number of beasts that would make interesting followers, which is exactly what Beast Master unlocks. You will now be able to take a freaking Brahmin with you. Who doesn't want a friendly two-headed cow to take down some mutants?
Craftable Ammo
You can now craft ammo. Here's to never again running out of rounds mid-fight.
Darker Nights
Just like Skyrim, the nights in Fallout 4 are way too bright for my liking. And just like Skyrim, you can install a wonderful mod called Darker Nights, which — unsurprisingly — makes the nights darker. You have a choice of just how dark you wish the nights to become too for some flexibility.
DEF_UI

This mod not only allows for the customization of the HUD (health, XP, V.A.T and other elements) but also the inventory and storage screens. It achieves something similar to that of Sky UI in Skyrim, making it much easier to manage everything, especially with a keyboard and mouse.
Full Dialogue Interface
This mod allows you to see exactly what your character is going to say in response to NPCs. When in a conversation in Fallout 4, it can prove frustrating to realize that your character's voice lines differ from selections on the dialog wheel. This is what Full Dialogue Interface addresses.
You will now be able to immerse yourself, knowing exactly what you're getting into.
Homemaker
Homemaker (also known as Expanded Settlements) is a mod for settlement Gods. Ideal for the creative mind, this mod allows for the creation of larger buildings with ease, not to mention new build sets for unique styling of settlements and a massive amount of objects that can be placed at secured locations. If you're a fan of the settlement system, you need this mod.
Improved Map with Visible Roads
The in-game map is handy to get around, but it doesn't show roads, which are far more important in the early game and on harder difficulty settings. Improved Map with Visible Roads does exactly what the name implies. It improves the map and adds roads across the board so you know where the nearest winding route of concrete is located.
More Where That Came From
The radio makes for more pleasant long journeys and adventures. With More Where That Came From installed, you'll want to rely on fast travel less in order to enjoy the 111 lore-friendly tracks added to the list of songs available for playback. This mod, in particular, adds all the tracks to the Diamon Radio station.
True Storms
True Storms is an exceptional mod, by the same modder who made the similarly named mod for Skyrim. This mod adds new weather patterns, sounds, visual effects, and other configurable details that give the wasteland some variability when venturing out the front gate.
Unlimited Settlement Objects
This one removes the maximum number of objects that can be placed in any one settlement. Enough said.
Unofficial Fallout 4 Patch
Bethesda games need some fixing, even after official patches have been released by the company. The same authors of the unofficial Oblivion and Skyrim patches return with the Fallout 4 patch. Hundreds of gameplay, quest, NPC, object, text, and placement bugs and issues are addressed in the mod.
It's safe to use and shouldn't break the game unless you have a ton of mods, where incompatibility may exist.
Worthy mention
The Fallout 4 Script Extender (F4SE) deserves a callout in our list, even though it's not technically available through Nexus. This handy tool allows for the installation and running of more powerful mods that can take advantage of even deeper hooks into Fallout 4.
