Paimon Launcher

Alternative launcher for GI, installs and updates the game, handles patches automatically. It's developed to run under Linux only.

Download manager Aria2c is used for improved download speed.

Updating the game


At start the launcher tries to detect game installation by looking in few common directories. If you have game installed but launcher didn't detected its installation path, click "Browse..." and choose the "Game" directory (where UnityPlayer.dll is located).

If you don't have game installed, launcher will offer to install it to default directory. Click "Browse..." if you wish to install to the different directory.


This launcher is built on Ubuntu 16.04 and tested on Ubuntu 16.04, 20.04, Fedora 34, Arch Linux. Other distributions should be supported as well. If you face a bug feel free to file an issue.

One-line installer with update support

In this way of installation the self update via "Settings -> Check for updates..." is supported.

To download and install launcher with just one line:

wget -qO- | bash -s - install

Or if you prefer curl instead:

curl | bash -s - install

After installation run launcher with Paimon_Launcher.AppImage.

If it doesn't start, try running it by full path: $HOME/.local/bin/Paimon_Launcher.AppImage .

Or just bare AppImage

Self-update is not supported if you downloaded and started AppImage. You still can check for updates and get redirected to download page from "Settings -> Check for updates...".

This app is distributed via AppImage.

  1. Download the latest archive from Releases
  2. Open Terminal
  3. cd ~/Downloads
  4. chmod +x Paimon_Launcher-[VERSION]-x86_64.AppImage
  5. ./Paimon_Launcher-[VERSION]-x86_64.AppImage

or read this article to learn how to do the same from GUI.

Build from sources

  1. Make sure build dependencies are installed. For deb systems run: sudo apt install build-essential git
  2. Clone this project using: git clone
  3. Download and start .
  4. You need to chmod +x qt-unified-linux-x64-* to start it.
  5. Register/sign in with free Qt account.
  6. Install version 5.15.2 of Qt only desktop (Desktop gcc 64-bit 5.15.2-0-....), you don't need any other packages to build this project.
  7. After Qt installation is finished, start Qt Creator and open from cloned directory
  8. Set up everything by default (Desktop 5.15.2)
  9. Choose target Release (Ctrl+T, Release) else updater will not be able to update Web version
  10. Build and run the project (Ctrl+R or the green triangle icon to the left bottom side)
