• it looks for PHP on your computer

• it installs Composer globally - just type composer from any location to use it
• it lets you use the Command Prompt, Git Bash, Msys, Msys2 and Cygwin (including cygwin php)
• it can be deployed unattended for silent installs/uninstalls

Download and run the latest release and in the majority of cases this is all you need to do. The install process is described in more detail below.

Composer-Setup is written with Inno Setup, which is a powerful free installer for Windows programs.

The first step is to find the location of your php.exe, which is the PHP command line interpreter. The installer searches common locations on your computer and presents you with its findings. If PHP is already in your path then it will display this value. If not, or you want to choose a different PHP, you must select from the list or hunt around manually.

The installer will then check that PHP and your path are set up correctly. If it finds any errors it will give you the chance to fix them.

Next, the installer will ask if you need a proxy server to connect to the internet. If it finds any values in your Internet Settings or your environment, then the proxy url will be displayed.

The installation directories depends on whether you are an Administrator or not and are non-negotiable.

Admin install for all users:

• C:\<Program Files>\ComposerSetup
• C:\ProgramData\ComposerSetup\bin

User install:

• C:\Users\<user>\AppData\Local\ComposerSetup
• C:\Users\<user>\AppData\Local\ComposerSetup\bin

After you have reviewed and accepted your settings, the installer will download Composer and set everything up. If your environment has been changed, it is important to close your current terminal and open a new one so that the changes get loaded. The installer will remind you if this is the case.

Composer-Setup creates a log file, which may be useful to review if you experience any issues. This is stored in your temp directory AppData\Local\Temp with a formatted filename: Setup Log YYYY-MM-DD #nnn.txt. Note that for Admin installs the log will be deleted on the next reboot.

The uninstall program is available from the Control Panel. Go to Programs and Features, select Composer, then click Uninstall. This offers the option to remove cache and configuration data that Composer may have stored.

The installer will modify your system path for Admin installs, or your user path for User installs. The installer will add the path to PHP if required and the path to the installation bin directory.

In addition the installer will add the following to the user environment:

• the C:\Users\<user>\AppData\Roaming\Composer\vendor\bin directory to your path
• an http_proxy value, if specified in the installer

The uninstaller will only remove the path to the installation bin directory and the Composer\vendor\bin path, leaving the PHP path and any http_proxy value intact.
