  • If disabling the antivirus software resolves the crashing issue, you can try creating an exception or adding Fallout 4 to the software’s whitelist or trusted applications list. This will inform the antivirus software that Fallout 4 is safe and should not be blocked.

Remember, antivirus software is designed to protect your computer from potential threats, so it’s important to weigh the risks when disabling or modifying its settings. If you continue to experience crashing on startup, it may be necessary to reach out to the antivirus software’s customer support for further assistance.

Disabling antivirus or firewall software, such as Windows Defender or third-party antivirus software, can help resolve Fallout 4 crashing on startup issues. However, it is crucial to exercise caution and consider the implications of leaving your system vulnerable to potential threats.

Delete Fallout 4 Configuration Files


When dealing with crashes on startup in Fallout 4, one troubleshooting method you can try is deleting the fallout4. ini file. This file contains various settings and configurations for the game, and deleting it can help resolve any issues that may be causing crashes.

Here are the key points to keep in mind:

  • Locate the fallout4.ini file: The fallout4.ini file can typically be found in the documents folder on your computer. Navigate to documents > my games > fallout4 to locate the file.
  • Make a backup: Before you delete the fallout4.ini file, it’s a good idea to create a backup copy. This way, you can easily restore the file if needed.
  • Delete the fallout4.ini file: Once you have a backup, go ahead and delete the fallout4.ini file from its location. By doing this, you are essentially resetting the game’s settings to default.
  • Launch the game: After deleting the fallout4.ini file, launch the game again and see if the crashing issue persists. In some cases, this simple step can fix the problem and allow you to play the game without any crashes.
  • Restore the file if necessary: If deleting the fallout4.ini file didn’t resolve the crashing issue or if it caused other problems, you can restore the backup copy you created earlier. Simply copy the backup file back into the fallout4 folder and overwrite the new file.

Deleting the fallout4. ini file can be an effective troubleshooting method for resolving crashes on startup in Fallout 4. Give it a try and see if it helps you get back to exploring the wasteland without any issues.

Disable Or Limit Background Programs

  • Type “%temp%” (without quotes) in the run dialog box and press enter. This will open the temporary files folder.
  • Select all the files and folders in the temporary files folder and delete them. You may encounter some files that are in use and cannot be deleted, which is normal.

Clear cache with CCleaner:

  • Ccleaner is a popular third-party tool that can help you clear cache and unnecessary files from your system. It provides an easy and effective way to clean up your computer and optimize its performance. To clear the cache using CCleaner, follow these steps:
  • Download and install CCleaner from the official website.
  • Launch CCleaner and navigate to the “cleaner” section.
  • Check the boxes next to the types of files you want to clean, such as temporary files, internet cache, and system logs.

Change Compatibility Mode And Run As Administrator

If you’re experiencing crashes on startup when launching fallout 4, changing the compatibility mode of the game can potentially resolve the issue. Compatibility mode allows you to run the game as if it were running on a previous version of windows.

Follow these steps to change the compatibility mode:

  • Right-click on the fallout 4 shortcut or executable file.
  • Select “properties” from the context menu.
  • In the properties window, navigate to the “compatibility” tab.
  • Check the box that says “run this program in compatibility mode for: “
