Windows tools

The app EXE doesn't need anything installed, but the Windows installers do:

Artifact	Tool	Command in PATH
Setup (.exe)	Inno Setup	iscc
MSI and MSM	WiX Toolset 4 or newer	wix
MSI and MSM	WiX Toolset 3	candle and light

If wix is in the PATH, JavaPackager uses it; otherwise it falls back to candle and light.

If you don't need an installer, disable it (generateSetup, generateMsi) or all of them (generateInstaller).

With Chocolatey

1. Install Chocolatey.

2. Run as administrator in CMD or PowerShell:

   choco install -y innosetup wixtoolset

This installs Inno Setup and WiX 3, and adds them to the PATH.

With Scoop

Scoop installs tools in your user folder and doesn't need administrator privileges.

1. Install Scoop.

2. Run in CMD or PowerShell:

   scoop bucket add extras
   scoop install inno-setup
   scoop install wixtoolset

This installs Inno Setup and WiX 3, and adds them to the PATH.

WiX 4 or newer

Chocolatey and Scoop install WiX 3. WiX 4 and newer are installed as a .NET tool, which needs the .NET SDK:

dotnet tool install --global wix

The wix command is then in the PATH.

note

Inno Setup 5 must be the Unicode version, because JavaPackager writes the Setup script in UTF-8. Inno Setup 6 is always Unicode.
