Silent mode installation

Theme: Configure
Who Is It For? System Administrator

What is it?​

Silent mode installation allows the Windows Agent to be installed without a graphical user interface, supplying all configuration values through command-line parameters. This method is used for scripted or automated deployments where presenting a graphical installer is not practical or permitted.

  • Automate agent installation across multiple machines without user interaction
  • Integrate agent installation into deployment pipelines and provisioning scripts

When to use​

  • When deploying the Windows Agent to multiple machines as part of a scripted provisioning workflow.
  • When the target machine has no interactive desktop session available during setup, such as during server builds or automated infrastructure provisioning.
  • When standardizing installation parameters across environments to ensure consistent configuration.

Benefits​

  • Eliminates manual steps during deployment, reducing configuration errors that can occur when responding to installer prompts interactively.
  • Enables repeatable, version-controlled agent deployments when silent installation parameters are stored alongside infrastructure configuration.

How to run a silent installation​

FAQs​

Can I use silent mode to upgrade an existing agent installation?
Yes. Use the same silent mode parameters with the upgrade installer to update the agent without a graphical interface. Refer to the OpCon Installation online help for parameter details specific to upgrades.

Does silent mode require the agent service to be stopped first?
For upgrades, stop the agent service before running the silent installer to avoid conflicts with files in use. For new installations, no existing service is present, so no pre-step is required.

Where are the installation logs written during a silent installation?
The InstallShield installer writes a log to the system's temp directory by default. You can specify an alternate log file path using a standard InstallShield logging parameter. Refer to the OpCon Installation online help for details.
