This package was approved by moderator AdmiringWorm on 6/18/2017.

This lightweight package performs an unattended installation of MSYS2 using official installer.
It is intended as an alternative to msys2 and msys2.install packages
which might be a better choice for some users.

Major differences when compared to MSYS2 package:
- Installation is performed from official .exe binaries instead of .tar.xz archives
- Unattended installation only without any additional customization or configuration (not even pacman --noconfirm -Syuu)

Major differences when compared to msys2.install package:
- msys2.install package is currently broken and not yet approved
- Support for unattended uninstall
- QtInstaller window is visible so that user can track progress and optionally answer MessageBox that is hard to automate (e.g. CorruptInstallationError)

To install MSYS2 Installer, run the following command from the command line or from PowerShell:

C:\> choco install msys2-installer

To upgrade MSYS2 Installer, run the following command from the command line or from PowerShell:

C:\> choco upgrade msys2-installer

Virus Scan Results

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.


This package has no dependencies.
