To run Fallout 3 smoothly in Windows 10, users simply need to run the game as an administrator or in compatibility mode. These methods won’t work for some users, they can instead try downloading the Games For Windows Live application or modifying the Falloutprefs.ini config file. Both of which are explained below.

GPU drivers can be updated using the below method:

We will discuss 4 different methods using which you can easily play Fallout 3 on your Windows 10 PC, so without wasting any time try these methods.

Method 1: Run As Administrator

In many cases, simply running the game as an administrator has been known to solve any and all the problems being experienced. Below is the method on how to always launch Fallout 3 as an administrator.

1. We start by navigating to the Fallout 3 folder on our systems. The folder is found within the Steam application.

2. Launch the Windows File Explorer by either double-clicking on its icon on your desktop or using the keyboard shortcut Windows key + E.

3. Navigate to either of the two paths mentioned below to locate the Fallout 3 folder:

This PC\C:\Program Files (x86)\Steam\steamapps\common\Fallout 3 goty

This PC\C:\Program Files (x86)\Steam\steamapps\common\Fallout 3

4. Alternatively, you can open the application (game) folder by right-clicking on the Fallout 3 application icon on your desktop and selecting Open File Location.

5. Find the Fallout3.exe file and right-click on it.

6. Select Properties from the following options menu.

Method 2: Run in Compatibility Mode

Apart from running as an administrator, users have also reported successfully being able to play Fallout 3 after running it in compatibility mode for Windows 7, the operating system for which the game was originally designed and optimized.

1. To run fallout 3 in compatibility mode, we will need to head back to the game folder and launch the properties window. Follow steps 1 to 4 of the previous method to do so.

2. Once in the Compatibility tab, enable ‘Run this program in compatibility mode for’ by ticking the box to its left.

3. Click on the drop-down menu below Run this program in compatibility mode for and select Windows XP (Service Pack 3).

Select Windows XP (Service Pack 3)

4. Click on Apply followed by OK.

5. We will need to repeat the above steps for two more files, namely, FalloutLauncher and Fallout 3 – Guardians of the eating kit.

So, go ahead and enable ‘Run this program in compatibility mode for’ for both these files and select Windows XP (Service Pack 3).

Finally, launch Fallout 3 to check if the error has been resolved. I hope you will be able to run Fallout 3 on Windows 10 without any issues. But if running Fallout 3 in compatibility mode for Windows XP (Service Pack 3) didn’t work, switch to compatibility mode for Windows XP (Service Pack 2), Windows XP (Service Pack 1) or Windows 7 one after the other until you are successful in running the game.

Method 3: Install Games For Windows Live

Playing Fallout 3 requires the Games For Windows Live application which is not installed by default on Windows 10. Fortunately, installing Games For Windows Live (GFWL) is quite easy and only takes a couple of minutes.

1. Click on the following URL (Download Games For Windows Live) and wait for your browser to complete downloading the installation file.

2. Click on the downloaded .exe file (gfwlivesetup.exe), follow the on-screen prompts/instructions, and install Games For Windows Live on your system.

3. Once installed launch Games For Windows Live by double-clicking on its icon.

4. The application will automatically download the files required to run Fallout 3 on your machine. Make sure your internet connection is working properly otherwise GFWL won’t be able to download the files.

5. Once all the necessary files have been downloaded by GFWL, close the application and launch Fallout 3 to verify if the error has been taken care of.

If the above didn’t work then you can crack the GFWL out of the Game. You need to use the Games for Windows Live Disabler from Nexus Mods or FOSE, the Fallout Script Extender modding tool to disable GFWL.

Method 4: Modify Falloutprefs.ini File

If you weren’t able to run Fallout 3 using the above methods, you will need to modify/edit a config file called Falloutprefs.ini that is required to run the game. Modifying the file is not a complicated task and requires you to merely type a single line.

  1. First, launch Windows File Explorer by pressing the shortcut Windows key + E. Under the quick access section, click on Documents.
  2. Inside the Documents folder, open My Games (or Games) sub-folder.
  3. Open the Fallout 3 application folder now.
  4. Locate the falloutprefs.ini file, right-click on it, and select Open With.
  5. From the following list of applications, select Notepad.
  6. Go through the Notepad file and locate the line bUseThreadedAI=0
  7. You can directly search for the above line using Ctrl + F.
  8. Modify bUseThreadedAI=0 to bUseThreadedAI=1
  9. If you can’t find the bUseThreadedAI=0 line inside the file, move your cursor to the end of the document and type bUseThreadedAI=1 carefully.
  10. Add iNumHWThreads=2 in a new line.
  11. Finally, press Ctrl + S or click on File and then Save to save all the changes. Close Notepad and launch Fallout 3.

If the game still doesn’t work as you wish it would, open the falloutprefs.ini in notepad again and change iNumHWThreads=2 to iNumHWThreads=1.

  1. Any of these methods is not working. The game runs for calm passages but when a fight starts the game just freezes. Bethesda should get involved here and release a patch.
    On PC (Steam) the file name is Fallout_default.ini
