Overview

LabTech can quickly and easily uninstall agents. This can be accomplished from the local machine by downloading the uninstall application from the Web Control Center or by issuing a command from the LabTech Control Center.

IMPORTANT: At this time, if you uninstall an agent that is acting as a network probe you will be unable to install a network probe at that location again. To ensure that the agent is not a network probe: in the Control Center, from the navigation tree, double–click a computer highlighted in blue and deselect the Network Probe checkbox in the right hand corner.

Uninstalling the Agent on a Local Machine

Use the uninstall application if you are uninstalling a corrupt agent, the agent is not accepting commands from the LabTech server, or the location has less than 10 agent machines.

1. Navigate to your LabTech server's Web Control Center. This can be accessed by entering your LabTech servers FQDN (http://labtechserver.fqdn).  Use https:// when applicable.

2. The uninstall application can be downloaded from the main page. Take note of where you download the file.
3. Right-click the uninstall application and select Run as administrator.
4. Windows will prompt you that a program is trying to make changes to your computer Click Yes to continue with the uninstall.

The process may take a few minutes. There will be no notification that the agent has been uninstalled. Typically, this is all that that is necessary to uninstall the agent. The system tray icon may still be visible until scrolled over with the mouse or the agent machine has rebooted.

Uninstalling Agents from the LabTech Server

If removing agents from multiple sites or several computers at once, the most efficient way is running the uninstall LabTech command from the LabTech Control Center.

NOTE: Ensure that the user has full permissions to access the client and run commands.

1. Open the LabTech Control Center.
2. From the navigation tree, right-click a client, location, or computer.
3. Select Commands > LabTech > Uninstall LabTech.

The next time the agents check in, the uninstall command will run. The system tray icon may still appear until scrolled over with the mouse or the agent machine has rebooted.

NOTE: You cannot execute additional commands after this command, as the agent will be shutting down.

Troubleshooting

If there is any doubt that the agent has not fully uninstalled, follow these steps to ensure full removal.

NOTE: Some of these files or directories may not exist if you have attempted to remove the agent before. If the directory or file does not exist, proceed to the next step.

1. On the remote agent machine, delete the %windir%\LTSVC directory.
2. Open the Registry Editor (Click Start, type regedit in the Search box and press [Enter]).
3. Expand HKEY_LOCAL_MACHINE > SOFTWARE. Delete the LabTech folder and all of its sub-folders.
4. Run the agent uninstaller.
5. When finished, restart the computer. This will remove all instances of the LabTech agent from the system.
