Commandline Installation

This document describes command-line installation, uninstallation, and deployment details for managing ARC installations across multiple PCs in schools or enterprise environments. It covers unattended (silent) installs, non-interactive uninstalls, installer options, and the product GUID used by deployment tools.

Install from the command line (unattended)

Use an unattended (silent) installation to install or upgrade ARC across many machines without interactive prompts. This is ideal for scripted, imaged, or centrally managed deployments.

Steps

  1. Open an elevated Command Prompt (Run as administrator) and change to the folder that contains the downloaded installer (for example, a USB drive, network share, or mapped drive).
  2. Run the installer with the quiet switch to perform a silent install:
"ARC Installer.exe" /quiet

The installer will run in the background and bypass interactive prompts, which speeds up updates and automated installations.

Tip: Ensure the installer binary is reachable from the target machine and that you have administrative privileges. If deploying over network shares, verify permissions and network connectivity before starting the installation.

Uninstall from the command line

To remove ARC non-interactively, run an elevated (administrator) Command Prompt and invoke the product uninstaller. The legacy WMIC tool can call the uninstall action for the registered product name:

WMIC product where name="ARC by Synthiam" call uninstall

WMIC queries installed products by their registered display name, so the name must match exactly. WMIC is deprecated on recent Windows versions; if WMIC is unavailable or you prefer a GUID-based uninstall, use msiexec with the product code (see the Product Code section):

msiexec /x {281E4CB7-6897-44DF-A347-1C28741536CF} /qn

Note: /qn performs a quiet uninstall. Verify that the GUID matches the installed package on your systems before running msiexec remotely or in scripts.

Installer options

The installer accepts additional command-line parameters for automation and customization. To view the full list of supported options and switches, run the installer with the /? parameter from a command prompt:

"ARC Installer.exe" /?
ARC installer command-line help output showing available switches and usage examples
Example: running the installer with /? displays available switches, logging options, and other automation parameters.

Use the listed switches to tailor installations at scale — for example, to specify silent install behavior, enable logging, or set custom installation targets. Include logging options when deploying broadly so you can capture and review any errors.

Product code (GUID) for deployment tools

When deploying ARC with Microsoft System Center Configuration Manager (SCCM) or similar tools, use the product code (GUID) to detect whether ARC is installed and to target upgrades or removals reliably.

ARC product code: 281E4CB7-6897-44DF-A347-1C28741536CF

SCCM and other deployment systems rely on this GUID to determine installation state, perform detection rules, and execute install/uninstall actions. Use the GUID in scripts or detection queries to avoid relying on display names.
