Offline Installation

In the Lumu Portal, you can find the .msi and .exe offline installer files recommended for an offline installation via command prompt.

The offline installer brings all files required for installation; no additional files are downloaded. The offline installer includes two components that allow you to install the Lumu agent or the agent updater independently.

The agent component is the Lumu sensor that collects the network-data, which is presented to your company at the Lumu Portal. The updater is the component in charge of periodically checking the server for the latest version of the agent, downloading and installing it.

If you want to have a silent deployment of the Lumu Agent (.exe)—installation process without any dialogs or user inputs—you should run the installer with the activation code of the group  and accept the license agreement. The silent installation command should look like this:
lum_agent_offline.exe /SP- /VERYSILENT /activationcode="[ActivationCode]" /acceptlicense="true"

The MSI installer only runs using a Windows command line. The installation parameters to deploy the MSI installer should look like this:

"C:\Windows\System32\msiexec.exe" /i lum_agent_offline.msi /quiet WRAPPED_ARGUMENTS="/activationcode=""[ActivationCode]"" /acceptlicense=""true"""

You can choose to install just a specific component and manage updates manually. To do that, you should indicate it through a command-line parameter COMPONENTS; this can be set as " agent " to install only the Lumu agent or "updater " to install the Lumu agent plus the updater. By default, the installer installs both components on your system.

The installation command with the component parameter should look like this:

lum_agent_offline.exe /SP- /VERYSILENT /activationcode="[ActivationCode]" /acceptlicense="true" /COMPONENTS=agent

This is how the command should look like for the MSI installer:

"C:\Windows\System32\msiexec.exe" /i lum_agent_offline.msi /quiet WRAPPED_ARGUMENTS="/activationcode=""[ActivationCode]"" /acceptlicense=""true"" /COMPONENTS=agent"

You have the option to run the command with “ /COMPONENTS=updater ” any time to install the updater using the same offline installer.

Command Quick Reference for Agent Support

The Lumu Agent includes an application for support purposes. You can use this application to troubleshoot and get agent information from devices.

The table below lists the available support commands for the Lumu Agent. You should run the commands in the Lumu installation path (e.g. C:/Program Files (x86)/Lumu/Agent ) using Command Prompt or Windows PowerShell with admin privileges.

lumu-agent-support [argument]



-h or --help

Print all the available commands with their description.


Print agent’s last status information, including its status, version, and settings.

--activation_code [arg]

Reset the activation code to the provided argument [ arg ]. This command is intended for correcting an activation code that is invalid or to reactivate an agent that was deleted by mistake. This will not change the activation code for an already successfully activated agent. To do so, you’ll need to delete it first from the portal and wait for the agent to disable itself or uninstall it. Command example:

lumu-agent-support --activation_code 5FDHjJWI

--proxy_list [arg]

Set the proxy configuration to the provided argument [arg]. The argument should be a colon-separated list of elements in the following format:

http://[<username>:<password>@]<ip address>:<port>

Command example:

lumu-agent-support --proxy_list http://user1:123@


Perform checks and print if the agent is running.

-v or --version

Show the support application version.

Repair, Update, or Reinstall Agent

The Lumu Agent installer (version 2.0+) brings the ability to repair, update, or reinstall the Windows agent.


To manually repair a Lumu Agent, simply run the installer that is the same agent version of the installed agent on the machine. The installer will prompt the following screen:
Lumu Agent repair window Lumu Agent repair window

The repair feature returns the agent to its default installation state. This feature should be used in cases such as when any file or registry was erased as the repair will retrieve the missing files. The repair process keeps the current agent configuration and activation code.


To update a Lumu Agent, run an installer from a more recent version of the installed agent on the machine. A screen with the new update option will display. This new feature allows you to upgrade your agent manually to a newer version.
The update also will repair any missing files or registries on the user machine.

Lumu Agent update window Lumu Agent update window


In both the repair and update process, you also have the option to reinstall a Lumu Agent.

The reinstall process will cause the current agent configuration and information to be deleted. 

To reinstall an agent, you will need to enter the same or a different activation code.
