Cross-Platform Mod Installer

Obtaining the Installer:


  1. Download the Windows Installer .zip file.
  2. Extract the zip file to a folder, with the following requirements:
    • The folder must be on the same drive (eg C: drive) as the game.
    • The folder must not require any special permissions for write access.
    • If you're not sure which folder to use, your Downloads folder will probably work fine, assuming it's on the same drive as the game.
  3. Run the file called install.bat

NOTE: If your operating system is 32-bit, you can use the 32-bit version of the installer

Using the installer

  1. Select which type of game you want to install (Umineko or Higurashi)
  2. The installer will attempt to auto-detect games it can patch
    • If your game is found, click on the path of the game you want to patch
    • If your game is not found, click "Choose Folder Manually" and manually select the game path
  3. Select which mod you want to install (eg full patch, voice only patch ...)
  4. Click 'OK' to begin the installation. The output will be shown on the terminal.
  5. Wait for the install to complete.
  6. Upon completion, the Umineko installer won't delete temporary files. This is so that you can re-install in the future without re-downloading. If you have verified your game works to your liking, you may wish to delete the temporary files, located in the temp folder of the game directory.
