Recently we’ve seen a lot of Fallout 4 players reporting an issue with their game. Their Fallout 4 doesn’t start when they try to launch it. If you’re experiencing this problem, don’t worry. You’re not the only one… We’ve put together some suggestions to help you fix the problem and get back to gaming. Here are a few things you can try:
  1. Restart your game
  2. Run your game in windowed mode
  3. Run your game in compatibility mode
  4. Update your device drivers
  5. Temporarily disable your antivirus software

Method 1: Restart your game

When you can’t open Fallout 4, the first thing you should try is to restart your game completely. To do this: 1) Exit your game and your Steam client. 2) Press the Ctrl, Shift and Esc keys on your keyboard at the same time to open Task Manager. 3) Close all Fallout 4 and Steam processes (by right clicking each of them and select End task or End Process).

Now try running your game and see if your issue is fixed. If you’re still experiencing this issue, don’t worry. We’ve got some other solutions you can try as well…  

Method 2: Run you game in windowed mode

You can also try running your game in a borderless windowed mode. Here’s how to do it: 1) Open your Fallout 4 launcher. 2) Click OPTIONS. 3) Check Windowed Mode and Broderless, then click OK.

4) Run your game and see if this solves your problem. If it does, great. But if not, there are still a few things you can try…  

Method 3: Run your game in compatibility mode

You may be having compatibility issues with your Fallout 4 so you can’t open it. To fix these issues, you should try running your game in compatibility mode. Here’s how you can do it: 1) Right click the executable (.exe) file or the shortcut for your game, then click Properties.

2) Click the Compatibility tab, check Run this program in compatibility mode, and click OK.

3) Run your game to see if this works for you. Hopefully it does. But if not, you may need to try a different solution.  

Method 4: Update your device drivers

It’s possible that your game isn’t running because you’re using the wrong device drivers or they’re out of date — especially video card drivers. Just in case this is the issue, you should update all your drivers and see if it fixes the problem. You can do this manually. of course. But if you don’t have the time, skills, or patience to update them yourself, you can do it with the help of Driver Easy. Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to be troubled by the wrong driver you would be downloading, and you don’t need to worry about making a mistake when installing. You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 steps (and you get full support and a 30-day money back guarantee). Here’s what you need to do: 1) Download and install Driver Easy. 2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to each driver to automatically download the correct version of this driver, then you can manually install it. Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).
You can do it for free if you like, but it’s partly manual.

Method 5: Temporarily disable your antivirus software

Your issue with Fallout 4 may be caused by interference from your antivirus software. To see if that’s the problem for you, you should temporarily disable your antivirus and check if the problem persists. (Consult the documentation of the program for instructions on disabling it.) If this resolves your problem, contact the vendor of your software and ask them for advice, or install a different solution.
Be extra careful about what sites you visit, what emails you open and what files you download when your antivirus software or firewall is disabled.
