Installing a Windows Agent

Warning

If you don't want to deal with AV flagging / deleting your agents, check the instructions for getting code signed agents.

You must add antivirus exclusions for the tactical agent.
Any decent AV will flag the agent as a virus, since it technically is one due to the nature of this software.
Adding the following exclusions will make sure everything works, including agent update:
C:\Program Files\TacticalAgent\*
C:\Program Files\Mesh Agent\*
C:\ProgramData\TacticalRMM\*
See here for other screenshot examples.

Dynamically Generated Executable

The generated exe is simply a wrapper around the Manual install method, using a single exe / command without the need to pass any command line flags to the installer. All it does is download the generic installer from the agent's github release page and call it using predefined command line args that you choose from the web UI. It "bakes" the command line args into the executable.

From the UI, click Agents > Install Agent.

You can also right click on a site > Install Agent. This will automatically fill in the client / site dropdown for you.

siteagentinstall

Powershell

The powershell method is very similar to the generated exe in that it simply downloads the installer from github and calls the exe for you.

Manual

The manual installation method requires you to first download the generic installer and call it using command line args. This is useful for scripting the installation using Group Policy or some other batch deployment method.

Tip

You can reuse the installer for any of the deployment methods, you don't need to constantly create a new installer for each new agent.
The installer will be valid for however long you specify the token expiry time when generating an agent.

Creating a deployment link is the recommended way to deploy agents. The main benefit of this method is that the executable is generated only whenever the deployment download link is accessed, whereas with the other methods it's generated right away and the agent's version is hardcoded into the exe. Using a deployment link will allow you to not worry about installing using an older version of an agent, which will fail to install if you have updated your RMM to a version that is not compatible with an older installer you might have lying around.

To create a deployment, from the web UI click Agents > Manage Deployments. managedeployments

Tip

Create a client / site named "Default" and create a deployment for it with a very long expiry to have a generic installer that can be deployed anytime at any client / site. You can then move the agent into the correct client / site from the web UI after it's been installed.

Copy / paste the download link from the deployment into your browser. It will take a few seconds to dynamically generate the executable and then your browser will automatically download the exe.

Optional Installer Args

The following optional arguments can be passed to any of the installation method executables:

-log debug

Will print very verbose logging during agent install. Useful for troubleshooting agent install.

-silent

This will not popup any message boxes during install, including any error messages or the "Installation was successful" message box that pops up at the end of a successful install.

-proxy "http://proxyserver:port"

Use a http proxy.

-meshdir "C:\Program Files\Your Company Name\Mesh Agent"

Specify the full path to the directory containing MeshAgent.exe if using custom agent branding for your MeshCentral instance.

-nomesh

Do not install MeshCentral agent during Tactical agent install. Note: Take Control, Remote Terminal and File Browser will not work.

You can get full command line options from (--help).

Scripting Agent Installation

If you want to deploy the TRMM agent using AD, Intune, Mesh, TeamViewer, Group Policy GPO, etc, this is a sample CMD script for deploying Tactical.

Install Scripts

Note

You will need to replace deployment url with your custom deployment URL:

@echo off

REM Setup deployment URL
set "DeploymentURL="

set "Name="
for /f "usebackq tokens=* delims=" %%# in (
    `wmic service where "name like 'tacticalrmm'" get Name /Format:Value`
) do (
    for /f "tokens=* delims=" %%g in ("%%#") do set "%%g"
)

if not defined Name (
    echo Tactical RMM not found, installing now.
    if not exist c:\ProgramData\TacticalRMM\temp md c:\ProgramData\TacticalRMM\temp
    powershell Set-ExecutionPolicy -ExecutionPolicy Unrestricted
    powershell Add-MpPreference -ExclusionPath "C:\Program Files\TacticalAgent\*"
    powershell Add-MpPreference -ExclusionPath "C:\Program Files\Mesh Agent\*"
    powershell Add-MpPreference -ExclusionPath C:\ProgramData\TacticalRMM\*
    cd c:\ProgramData\TacticalRMM\temp
    powershell Invoke-WebRequest "%DeploymentURL%" -Outfile tactical.exe
    REM"C:\Program Files\TacticalAgent\unins000.exe" /VERYSILENT
    tactical.exe
    rem exit /b 1
) else (
    echo Tactical RMM already installed Exiting
Exit 0
)
Invoke-WebRequest "<deployment URL>" -OutFile ( New-Item -Path "c:\ProgramData\TacticalRMM\temp\trmminstall.exe" -Force )
$proc = Start-Process c:\ProgramData\TacticalRMM\temp\trmminstall.exe -ArgumentList '-silent' -PassThru
Wait-Process -InputObject $proc

if ($proc.ExitCode -ne 0) {
    Write-Warning "$_ exited with status code $($proc.ExitCode)"
}
Remove-Item -Path "c:\ProgramData\TacticalRMM\temp\trmminstall.exe" -Force
  • Use Agents menu > Manage Deployments
  • Generate a deployment link with an expiry date set to very far in the future, then access the link to download the executable.
  • Create the msi
  • Apply via GPO software deployment to the appropriate machines

Script for Full Agent Uninstall

You can always use this to silently uninstall the agent on workstations:

"C:\Program Files\TacticalAgent\unins000.exe" /VERYSILENT

Reinstalling Mesh and Reconnecting to TRMM

Run this from Send Command:

"C:\Program Files\TacticalAgent\meshagent.exe" -fullinstall

Then use Agent Recovery > Mesh Agent, and choose Recover:

Stuck at "Downloading mesh agent..."?

Make sure TRMM can connect to Mesh. Run:

/rmm/api/env/bin/python /rmm/api/tacticalrmm/manage.py check_mesh

If there's an error, make sure you have it setup correctly.

Install Linux Agent (beta)

To install:
1. Go to rmm.yourdomain.com and login.
2. Click on Agents > Install Agent.
3. Choose the Client, Site, Server or Workstation and Architecture (change expiry if required) as well as Linux.
4. Click Download.
5. If downloaded on the Linux machine you want to add as an agent (otherwise copy to machine using WinSCP or similar) open terminal.
6. cd to the folder you have downloaded the script to.
7. Run chmod +x rmm-clientname-sitename-type.sh
8. Run sudo ./rmm-clientname-sitename-type.sh and wait for script to complete.

If you changed the expiry time you could upload the script to any accessible server and deploy to multiple devices.

Currently there are no deploy links for Linux agents however you could use the following method if uploaded somewhere (website etc).

An example deployment script would be (note there's an install token in that script, so delete it when done if you're concerned):

wget scripturl
chmod +x rmm.sh
./rmm.sh
