Install the Desktop Application

The easiest way to run the TASSEL desktop application is with a native installer. These installers are produced by jDeploy and bundle a compatible Java runtime, so you do not need to install Java separately.

Installers are attached to each versioned release, alongside the standalone archives, so the installer you download records the exact TASSEL version it installs.

Just want the download?

Visit the Download page. It auto-detects your operating system and offers the correct installer, plus every other build.

Choose your platform

Every installer filename includes the TASSEL version, so pick the asset for your platform from the latest release:

Platform File type
macOS (Apple Silicon) TASSEL.5.Installer-mac-arm64-...tgz
macOS (Intel) TASSEL.5.Installer-mac-x64-...tgz
Windows (64-bit) TASSEL.5.Installer-win-x64-...exe
Linux / Unix TASSEL.5.Installer-linux-x64-...tar.gz

macOS

  1. Download the TASSEL.5.Installer-mac-arm64-...tgz asset if you have Apple Silicon (M1/M2/M3 and newer), or TASSEL.5.Installer-mac-x64-...tgz for Intel. Not sure which you have? Click the Apple menu → About This Mac and check the Chip / Processor line.
  2. Double-click the downloaded .tgz to expand it, then open the resulting app.
  3. If macOS Gatekeeper blocks the app because it is from an unidentified developer, right-click (or Control-click) the app and choose Open, then confirm. You only need to do this the first time.

Windows

  1. Download the TASSEL.5.Installer-win-x64-...exe asset.
  2. Run the .exe. If Windows SmartScreen appears, choose More info → Run anyway.
  3. Follow the prompts. TASSEL is added to the Start menu when the installer finishes.

Linux

  1. Download the TASSEL.5.Installer-linux-x64-...tar.gz asset.

  2. Extract the archive:

    tar -xzf TASSEL.5.Installer-linux-x64-*.tar.gz

  3. Run the extracted launcher to start TASSEL.

Updating

The installer asks how you want updates handled, defaulting to tracking stable releases. With that default, TASSEL updates itself when a newer release is published, so you do not need to download an installer again. You can always install a specific build from the GitHub releases page.

Already have an app named TASSEL 5 main?

Installers from 5.2.97 and earlier registered the application as TASSEL 5 main, because they were built from the main branch rather than a version. From 5.2.98 onward it is registered as plain TASSEL 5. Your operating system treats these as two different applications, and the old one will not receive further updates, so uninstall TASSEL 5 main once and then run the current installer.
