Recommended Installation Location

A clean installation is not only required to get rid of any potential leftover mod files, but also to make sure the game is installed in a safe location. Here is what you need to know when choosing where to install your game:

Uninstalling the Game

If you do not have the game installed yet, skip this step.

As the game is available on both Steam and GOG, there are separate instructions here for each version. You obviously only need to follow the directions for the version you have.

For Steam:

  1. Open Steam and go to your Library
  2. Find Fallout: New Vegas in the list
  3. Right-click on it and select Manage -> Uninstall
  4. Navigate to Steam\steamapps\common\ and, if present, delete the Fallout New Vegas folder
  5. Navigate to Documents\My Games\FalloutNV and delete all the files ending in .INI

For GOG:

  1. Open GOG and go to your Library
  2. Find Fallout: New Vegas in the list
  3. Right-click on it and select Manage Installation -> Uninstall
  4. Navigate to where the game is installed (GOG Galaxy\Games by default) and, if present, delete the Fallout New Vegas folder
  5. Navigate to Documents\My Games\FalloutNV and delete all the files ending in .INI

Making a New Steam Library

If you already have a Steam library set up outside of any default Windows folder, or you have the game on GOG, skip this step.

A new Steam library needs to be set up to install the game on, as the default library is in a default Windows UAC-protected folder (C:\Program Files x86\Steam).



  1. Open Steam and select Steam -> Settings in the top left
  2. In the Downloads tab, select Steam Library Folders
  3. Select Add Library Folder and select a location outside of any default Windows folders
IMPORTANT: By default, Steam only allows one library per drive, but there is a workaround. If for example you already have the default Steam library at C:\Program Files x86\Steam, but still want your game on your C:\ drive, you will need to follow these instructions to do so.
  1. Exit out of the settings when you are finished

Installing the Game

For Steam:

  1. Open Steam and go to your Library
  2. Find Fallout: New Vegas in the list and select Install
  3. From the install pop-up, set the location for install to the Steam library you just created in the previous step
  4. Select Next then wait for the install to finish

For GOG:

  1. Open GOG and go to your Library
  2. Find Fallout: New Vegas in the list and select Install
  3. Set the Install to location to a folder outside of any default Windows folders

Post-Installation

Key Terminology

Now that the game is installed, there are two folders from it that will be referred to in the guide often:

Enabling File Extensions

By default, Windows Explorer will not show file extensions (such as .exe, .dll, or .esp). These extensions are very important when going through the guide, so it is highly recommended to enable file extensions:


  1. Open Windows Explorer
  2. Select the View tab at the top
  3. Check the box next to File name extensions
  4. show file extensions

Generating Fresh .INI Files

  1. Run FalloutNVLauncher.exe from the game's Root folder
  2. Click OK to both pop-ups that say Detecting Video Hardware
  3. Select Options then select the Ultra preset option
  4. Set the Resolution option to your preference (the launcher usually does not set it to your monitor's max resolution)
  5. Click OK then Exit
