    Linux Users: GNOME Desktop and Ubuntu causes Game Crash - Workaround

    GNOME Desktop (the default on Ubuntu) will cause Higurashi Ep.4 and upwards to crash the entire desktop. This happens even on the base game (without any mods applied). A workaround for this is to install XFCE desktop. You can follow this guide to install XFCE desktop (it can be installed alongside GNOME). Please make sure you can launch the base game before applying any mods (for ease of installation, please don't make any saves on the base game).

    1. Install the following using your distribution's package manager:
      • Python (2 or 3)
      • Python Tkinter
        • Ubuntu: sudo apt-get install python-tk
        • Arch Linux: sudo pacman -S tk
        • Fedora: sudo dnf install python2-tkinter or
          sudo dnf install python3-tkinter
        • If your distribution is not listed, you may need to lookup how to install tkinter on your particular distribution
    2. Download and extract the Linux Installer
    3. Run the shell script called install
  2. Opening the installer will launch a page in your browser. Do not close this page.

  3. On the web page that was just launched, click on the game you want to mod.
  4. Fill in your game path, and mod options as applicable, then start the installation.

    Mac - If path auto-detection fails - Finding Game Path Manually

    If game path auto-detection fails, you can follow these instructions to find the game path:

    1. Click the big green "Select Application (.app file) Manually (Open File Dialog)" button, just below the path entry textbox.
    2. A Finder window entitled "Please choose a game to install to" will open. We will leave it for now, but need it later so don't close it
    3. Open Steam, and navigate to your game list
    4. Right-click on the game you want to mod in the game list, and select "Properties"
    5. Navigate to the "LOCAL FILES" tab of the window that popped up
    6. Click "Browse Local Files". Another finder window will pop up, showing the game files.
    7. Locate the "Umineko1to4"/"HigurashiEp0X" file, which should visually have a proper game icon. Ignore the other files without a proper icon. These files have the ".app" extension, but the extension may be hidden.
    8. Drag and drop the file onto the previously opened "Please choose a game to install to" Finder Window
    9. Click the "Choose" button

    For reference, the default steam folder is ~/Library/Application Support/Steam/steamapps/common/, but yours may be different.

  5. To stop an install that is in progress, you MUST close the terminal window (the black box with lots of text).

  6. Carefully read the information that appears once the install has finished.

Installer FAQ and Troubleshooting

Can't launch installer - I get a http.client.UnknownProtocol: HTTP/2.0 error when using a VPN or proxy

Please try running the installer without going through a VPN or proxy. Some company/school networks may also cause the same error, as they act as a proxy.

Specifically, "UltraSurf VPN" is known to cause this problem.

Installer crashes on launch - The log has a "TimeoutError: [WinError 10060] A connection attempt failed ..."

Please check if any antivirus/firewall software is blocking the installer. "Comodo Firewall" is known to cause this issue.

Please move the installer .exe to a fresh subfolder and run it from there. This forces a fresh re-extraction of the installer files.

Download stage of installer fails - I get a SSL/TLS handshake failure from Aria2c

Some users have reported getting the following error (will appear in the log):

SSL/TLS handshake failure: Error: The revocation function was unable to check revocation because the revocation server was offline.

The following may help you fix this issue:

  • Disable any VPN or proxy you are using, or try a different internet connection if you are at a school/hotel/business etc.
  • If you have any Windows updates in-progress, let them fully complete before running the installer (including required restarts)
  • Reboot your computer, then try running the installer again


This installer is currently in development. You might find bugs, and things might not always work - We would be grateful if you report bugs on Github or our Discord server.
