Maestro Silent Install

A silent install of Maestro isn’t interactive and must have parameters preset through the command line. Only perform a silent install of Maestro when you’re faced with scenarios where an interactive install isn’t an option, such as when building virtual machine images.


We recommend opting for the regular, interactive installation process whenever you can. A regular install of Maestro will involve an installation wizard that guides you through the installation process.

Before you proceed:

Base Command

The following command installs the Crawling Module in the US East region with default ports for Maestro and its workers:


The /VERYSILENT, /SUPPRESSMSGBOXES, and /NORESTART Inno Setup flags are mandatory.

/LOG=log.txt creates a log file with details pertaining to the process, which could be relevant for troubleshooting.
