Windows MSI 64-bitinstaller for the Thunderbird release update channel. We also offer localized MSI installers for the Thunderbird Beta and Thunderbird Daily update channels (note that Thunderbird Daily is an unstable testing and development platform not intended for production environments; make sure to back up important data regularly!).
INSTALL_DIRECTORY_PATH="path"path (quoted string): Absolute folder path specifying the complete install location. This folder does not need to exist already (but it can). If INSTALL_DIRECTORY_NAME is set, then this setting will be ignored.
INSTALL_DIRECTORY_NAME="name"name (quoted string): Name of the installation directory to create within Program Files folder. For example, if INSTALL_DIRECTORY_NAME is set to "Thunderbird Release", then the installation path will be something like "C:\Program Files\Thunderbird Release". The Program Files path used will be the correct one for the architecture of the application being installed and the locale/configuration of the machine; this setting is mainly useful to keep you from having to worry about those differences. If this is set, then INSTALL_DIRECTORY_PATH will be ignored.
DESKTOP_SHORTCUT=true|falseSet to false to disable creating a shortcut on the desktop. true by default.
START_MENU_SHORTCUT=true|falseSet to false to disable creating a Start menu shortcut. true by default.
INSTALL_MAINTENANCE_SERVICE=true|falseSet to false to disable installing the Mozilla Maintenance Service. This will effectively prevent users from installing Thunderbird updates if they do not have write permissions to the installation directory. true by default.
REMOVE_DISTRIBUTION_DIR=true|falseSet to false to disable removing the distribution subfolder from an existing installation that’s being paved over. By default this is true and the folder is removed. The default folder path of the distribution subfolder is "C:\Program Files\Mozilla Thunderbird\distribution\".
PREVENT_REBOOT_REQUIRED=true|falseSet to true to keep the installer from taking actions that would require rebooting the machine to complete, normally because files are in use. This should not be needed under normal circumstances unless you’re paving over a copy of Thunderbird that was running while the installer was trying to run, and setting this option in that case may result in an incomplete installation. false by default.
OPTIONAL_EXTENSIONS=true|falseSet to false to disable installing any bundled extensions that are present. true by default.
EXTRACT_DIR="directory"Extract the application files to the given directory and exit without actually running the installer. Of course, this means all other options will be ignored.
