# 1 Installing the Binary Release

### 1.1 Windows

The system is delivered as a Windows Installer executable. Get it from http://www.erlang.org/download.html

#### Installing

The installation procedure is automated. Double-click the .exe file icon and follow the instructions.

#### Verifying

- Start Erlang/OTP by double-clicking on the Erlang shortcut icon on the desktop.

  Expect a command-line window to pop up with an output looking something like this:

        Erlang/OTP 17 [erts-6.0] [64-bit] [smp:2:2]

        Eshell V6.0  (abort with ^G)
        1>

- Exit by entering the command halt().

        2> halt().

  This closes the Erlang/OTP shell.
