Issues fixed[edit]

TweakGuides has created a comprehensive guide for fixing issues in this game. It can be found here.

Characters "Throwing Up"[edit]

This is caused by conflicting character mods, this can usually be fixed with a compatibility patch or by using BOSS to fix the load order.

Game Crashes Randomly[edit]

Random Crashes[citation needed]
  1. Try NV Stutter Remover

Game Stuck On Loading Screen[edit]

Perpetual loading screen.
Sometimes attempting to 'load' a save game does not work.
Generate New Autosave
  1. Start a new game and playing it to the point where Doc Mitchell tells you to go to the Vigor Tester machine.
  2. At this point the game will autosave, and loading your previous save should work now.
Load a different save first
  1. Load an older save (or different save).
  2. At this point the engine and game are fully loaded, loading your previous save should work now. This is faster than having to skip cutscenes and wait for an autosave, but requires having other saves on your hard drive.

Unable To Level[edit]

Caused by using adlevel console command.
rewardxp console command[9]
Can be fixed by adding enough XP to level once again.
  1. Use the console command rewardxp (e.g. rewardxp 5000 to award 5000xp) and add enough XP to level once again.

Some Sounds Don't Work[edit]

Voice acting and Pip-Boy sounds (and possibly others) can not be heard, while the radio and movement can.
Windows Sound Options[citation needed]
Can be fixed by correcting the number of sound channels in the configuration of your playback device in Windows.

Application load error P:0000065434[edit]

This happens when you start the launcher.
Launcher doesn't open[citation needed]
  1. Open Steam as Admin.
  2. Rightclick the game in your Steam library and select "Properties".
  3. Select the tab "Local content" and click "Verify integrity of game cache". This might be necessary several times. Steam will download the missing/corrupt files.
Launcher can't find Steam
  1. Open CMD in Admin-mode
  2. Go to your New Vegas installation directory (the same directory where NVSE resides)
  3. Create a symbolic link to Steam by typing this command in CMD: mklink "Steam.exe" "C:\Program Files (x86)\Steam\Steam.exe"

Game Crashes on Startup (NVSE installed properly)[edit]

This happens when you start the game, and have mods that utilize NVSE. (New Vegas Script Extender)
Crashes on Startup (NVSE installed properly)[citation needed]
  1. Rightclick nvse_loader in the Fallout New Vegas installation folder and select properties.
  2. Select the tab "Compatibility" and click "Run this program as administrator" and apply.
This could also be the result of mods attempting to change the same object.

Player "Sliding"[edit]

Character will continue to move or "slide" a bit sometimes even after they have stopped moving. Note that this should not be confused for the game engine forcing characters to take a full step when moving.
Player "Sliding"
  1. Open Control Panel.
  2. Navigate to Keyboard settings (NOTE: You may have to change your view from "Category" to "Icons" in order to access Keyboard settings)
  3. Under the "Speed" tab, set Repeat Delay to Short, and set Repeat Rate to Slow.
This fix does not work for some players. If you know of a solution, please add it to this section.

Data Files get auto loaded on Startup[edit]

Affected data files are enabled at all times, even if their boxes in the "Data Files" menu are unticked.
Disable data file autoloading
  1. Go to the <path-to-game>\Data\
  2. Search for a file you want disabled with a .nam extension.
  3. Rename or delete the selected file.
  4. Repeat for any file you want disabled.
If you chose to delete the .nam files, you can recover them by verifying the game data files integrity in Steam.

Application load error 5:0000065434[edit]

Occurs when launching the game in any other way than through Steam due to an inappropriate Steam AppID being used.
Can happen when you have a Polish, Czech or Russian version of the game.
Error code P:0000065432 may also apply when the AppID is incorrect.
Installation of Fallout NV Extenders[citation needed]
  1. Download New Vegas Script Extender
  2. Install the New Vegas Script Extender according to the ReadMe file found in the archive you just downloaded.
  3. Download 4GB Fallout New Vegas.
  4. Install 4GB Fallout New Vegas by extracting all .dll and .exe files from the archive you just downloaded into your Fallout NV installation folder.
  5. Create a shortcut to fnv4gb.exe in your Fallout NV directory and add -SteamAppId 22490 as a launch parameter. The shortcut should now resemble:
    "C:\Program Files (x86)\Steam\steamapps\common\Fallout New Vegas enplczru\fnv4gb.exe" -SteamAppId 22490
  6. Use this shortcut command line as an example. It can be used to launch the game through Nexus Mod Manager, Mod Organizer and possibly other launchers.


This method only applies to PL/CZ/RU versions of the game. If it fails, try one of the methods below.
This method involves installing two extensions. While being mods, they are considered essential.
Match shortcut target AppID with actual Steam AppID
  1. Download New Vegas Script Extender
  2. Install the New Vegas Script Extender according to the ReadMe file found in the archive you just downloaded.
  3. Download 4GB Fallout New Vegas.
  4. Install 4GB Fallout New Vegas by extracting all .dll and .exe files from the archive you just downloaded into your Fallout NV installation folder.
  5. Find the correct Steam AppID for your version of the game. The easiest way to do this is as follows:
    1. Right click the game within Steam, then select "Create Desktop Shortcut."
    2. Right click the newly created shortcut on your desktop and select properties.
    3. The URL address should be in the form of steam://rungameid/22380, with the last number being the real Steam AppID.
  6. Create a shortcut to fnv4gb.exe in your Fallout NV directory and add -SteamAppId xxxxx as a launch parameter. Replace "xxxxx" with your real AppID. Shortcut should now resemble:
    "C:\Program Files (x86)\Steam\steamapps\common\Fallout New Vegas\fnv4gb.exe" -SteamAppId 22490
  7. Use this shortcut command line as an example. It can be used to launch the game through Nexus Mod Manager, Mod Organizer and possibly other launchers.


This method applies whenever the AppID being launched does not match your Steam installation, such as any localized version of the game or a special edition of the game.
As above, this method involves installing two extensions. While being mods, they are considered essential.
Symbolic link creation[10]
  1. Open a Command prompt using "Run as Administrator" (Start>All Programs>Accessories>Command prompt).
  2. At the prompt type, enter the complete path to the common folder inside the SteamApps folder you use. For example,
    CD "C:\Program Files (x86)\Steam\SteamApps\common\"
    and press Enter (if the common folder does not exist, create it).
  3. The command prompt should show the above path. If not, try the following steps. Otherwise, skip to Step 4.
    1. First, check to see if the path you entered exists.
    2. Second, if the path exists, check to see if the drive letter of the path is different than C. If so, in addition to navigating to the folder, you must also enter the drive letter and press Enter in order to see the path you entered. For example,
  4. Next, type
    mklink /d "Fallout New Vegas" "D:\Steam\SteamApps\common\Fallout New Vegas"
    and press Enter (change the example path to your Fallout New Vegas installation folder).
  5. Recreate any shortcuts using the new "proper" path (i.e. C:\Program Files (x86)\Steam\SteamApps\common\Fallout New Vegas\FalloutNVLauncher.exe).
  6. Reconfigure your mod managers to also include the changed path.


This method creates a symbolic link between where the game is installed, and where it "thinks" it is installed. It allows using the correct path without moving the game files.
Game reinstallation[citation needed]
  1. Uninstall the game.
  2. Install the game, this time in the default Steam folder. This is frequently:
    C:\Program Files (x86)\Steam\SteamApps\common\


This method moves all the game files to the default Steam folder. Make sure you have enough disk space before doing this.

Tilde console key not working[edit]

Pressing the tilde key on the keyboard does not launch the cheat console.
Disconnect gamepad
  • Can be fixed by disconnecting the controller. The controller can be reconnected after using the cheat console.
