From version v1.15, Elixir now provides pre-compiled and offline installers for Windows per Erlang/OTP version. See the official website for all up to date install instructions.

• Downloads and installs the latest Elixir version, or another version the user selects
• Offers to install Erlang and add the Erlang directory to the system's Path variable
• Adds Elixir to the system's Path variable
• Creates Start Menu shortcuts

The offline installer (Elixir.iss) packages a specific Elixir release to install, and also can append the system's Path variable appropriately. This kind of installer is currently not distributed in binary form.

The web installer (ElixirWeb.iss) is what's currently distributed (see Releases). The web installer itself does not install Elixir. It packages the files necessary to download, compile, and run the offline installer for the selected Elixir release. It also handles installing Erlang and adding it to the system's Path variable.

If you need to install Elixir on a system without internet access, follow these steps:

1. Install Erlang on to the system.
2. On another system with internet access, run elixir-websetup.exe.
3. When prompted, check the box for "Defer installation (advanced)" and uncheck all other options.
4. Proceed with the installation wizard. Once complete, elixir-vX.Y.Z-setup.exe will be placed in the same folder as elixir-websetup.exe.
5. Use elixir-vX.Y.Z-setup.exe to install Elixir on to the system. (Note: You may wish to uninstall previous versions of Elixir before doing this.)

First, download the Unicode version of Inno Setup (isetup-X.Y.Z-unicode.exe from jrsoftware.org) and install it, making sure to keep the "Install Inno Setup Preprocessor" checkbox checked when asked. Then, clone this repo (elixir-windows-setup) to your system.

To build the web installer, open elixir-windows-setup\ElixirWeb.iss in the Inno Setup Compiler and click "Compile" to build an installer in elixir-windows-setup\Output.

To build the offline installer follow these steps:

1. Extract Precompiled.zip of the desired Elixir Release into elixir-windows-setup\elixir
2. Open elixir-windows-setup\Elixir.iss in the Inno Setup Compiler.
3. Click "Compile" to build an installer in elixir-windows-setup\Output.
