How to find Epic Games Launcher installer logs

To generate Epic Games Installer logs:


  1. Place the Epic Games launcher installer .msi file on the root of the C: drive.
  2. Press Windows Key + R and enter the following:
    • msiexec /i C:\EpicGamesLauncherInstaller.msi /L*V C:\EpicGamesInstallerLog.txt
    • Use the exact name of the installer msi file in place of "EpicGamesLauncherInstaller.msi"

      Note: Please make sure you include the .msi suffix when running the command; otherwise, you may experience errors while running the installer.
  3. Once the command is entered, press CTRL + SHIFT + ENTER to run it as an administrator.

This will run the installer and generate a log file called EpicGamesInstallerLog.txt. This will be saved on the root of your C: drive. Once you locate the text file attach it to your ticket if you have one and we’ll be happy to help you further.


  1. Open a terminal and enter the following line: open /Applications/Epic\ Games\ --args -debuglogging
