Silent Command-Line Installation
Let's suppose you have several computers around the world on which you
want to install EFT. You can provide to each of the remote sites an installation
file with a batch file, then ask a local administrator to execute the
batch file, which will install EFT. The script silently installs/upgrades
EFT without any interaction on the part of the administrator. The installer
logging functionality can be used to verify the outcome and diagnose potential
issues. You can also upgrade silently from the command line and install
the administration interface from a command line.

If you install EFT HA via the silent installer, then, once configured, if you upgrade EFT via the install wizard, EFT fails to start the server service. The install wizard is setting the EFT server configuration details to the default paths.
This issue only occurs when you use the silent installer for the initial deployment, then follow with an upgrade using the wizard. If you use the wizard for both installing and upgrading, or the silent installer for both installing and upgrading, this issue does not occur.
