Coco blockquote
Only Steam (Global) and GOG copies of the game are supported!


  1. Download the latest Wabbajack.
  2. Create a new folder anywhere outside of any default Windows folders, and the game folder itself.
    Example: C:\Modding\Wabbajack
  3. Place the downloaded Wabbajack.exe in this folder, then run it.
  4. Click Browse Modlists, then locate Viva New Vegas in the gallery and click the download button in the corner.
  5. In Installation Location select an empty folder that is NOT the following:
    • The Steam folder,
    • Any default Windows folders,
    • The game folder,
    • The folder where you put Wabbajack.exe.
    Example: C:\Modding\Viva New Vegas
  6. Begin the installation.
  7. Accept the Nexus Mods API request.
  8. If you are not a Premium user you will need to manually click download for each mod.
  9. Once complete, the installation will show a green Installation Complete screen.
    • If you see a red Installation Failed screen, try log-in again through the Wabbajack settings, then reinstall the list to the same folder. If that doesn't work please join the ModdingLinked Discord server for support.

Post-Install Steps


  1. Open Windows Security.
  2. Open Virus & threat protection.
  3. Click Manage settings under Virus & threat protection settings.
  4. Scroll down and click Add or remove exclusions under Exclusions.
  5. Add a Folder exclusion and point it to the Installation Location folder.
This operation is required because Windows can block MO2 and mod files from loading due to how MO2's virtualized filesystem works.

If you are using a third-party antivirus, you will need to find the exclusions menu and add one to the same folder.

Root Mods

  1. In your Installation Location, open the Root Mods folder.
  2. Copy everything to the game's Root folder.
  3. Still in the game's Root folder, double-click on FNVpatch.exe to run it.
  4. A command prompt window will open and should say FalloutNV.exe patched!.
  5. Close the command prompt and a file named FalloutNV_backup.exe should appear in the game's Root folder.

BSA Decompressor (Optional but Recommended)

Decompresses the vanilla BSA files to reduce loading times and stuttering. Can also fix certain sound effects not playing.
  1. In your Installation Location, open the BSA Decompressor folder.
  2. Run FNV BSA Decompressor.exe.
  3. The Fallout: New Vegas and Decompressed Archives paths should be filled by default (Root folder and Data folder respectively).
    If they aren't, close the program and re-run your game launcher to generate the required registry key,
  4. Click Decompress, wait for the process the finish, then exit the program once finished.

Launching Mod Organizer 2

  1. Launch ModOrganizer.exe from your Installation Location.
  2. If you see a pop-up called FalloutNV_lang.esp was found, select Yes.
  3. If you see a pop-up called Register?, select Yes.

Configuring Game's Settings

  1. Launch the game launcher using the Fallout Launcher option in MO2.
  2. Run the launcher through MO2
  3. Inside the launcher, click Options and do the following:
    1. Select Ultra Preset.
      If you have a very weak PC, you can select Medium Preset instead.
    2. Set Resolution to your monitor's native resolution.
      Launcher's resolution list can be pretty limited - if your resolution is not present, you can set it manually by following these steps:
      1. Click the MO2 INI button button at the top of MO2 and select INI Editor.
      2. Select the FalloutPrefs.ini tab.
      3. Change following settings in the Display section:
        iSize W = your screen width
        iSize H = your screen height
  4. Close the launcher.

Performance and Stability Guide

Coco blockquote
Information for AMD users!
Use the hot-fix driver to avoid crashes, or use DXVK in accordance with the following guide.
Your game will not launch without either of these.
In-depth guide about how to fix the game's lackluster performance, display issues and alt-tabbing. Covers topics such as DXVK, framerate limiting, display modes, lag and HDR.

Launching the Game

Go to the modlist's Installation Location folder you chose at the beggining and run ModOrganizer.exe.
If you are planning to install texture mods, enable the NVTF - Texture Modding Preset mod in the Utilities separator!

To run the game, use the New Vegas executable in Mod Organizer 2.

Run New Vegas through MO2

You can use the Shortcut drop-down to create Desktop and Start Menu shortcuts, this will allow you to launch the game without opening the MO2 GUI.

This Wabbajack list already comes with decompressed plugins and better LOD.

Updating the List

  1. Verify files on Steam or GOG Galaxy.
  2. Reinstall the list from the Wabbajack tool and enable the "Overwrite Installation" checkbox.
  3. Reapply the 4GB Patch, optionally the BSA Decompressor as well (instructions for both are provided above).

Finishing Notes

You have now installed the full Viva New Vegas modlist and you can enjoy the game. You may want to add your own mods on top of the modlist, but that is only recommended if you are an experienced modder since you need to know how to use FNVEdit and The Method and have good general knowledge of many game systems.

And remember, we may not provide support for setups that have added mods, especially if you went overboard.
