Antivirus Recommendations

  • Set an exception in your antivirus or anti-malware scanning software for the ContegoSPOP folder where the LEM Agents will be installed. The alerts are kept in queue files, which change constantly as they are normalized and encrypted.
  • Turn off any anti-malware or endpoint protection applications on host systems during the installation process, as they can affect the process by which installation files are transferred to the hosts.


Uninstall the old version of the LEM agent before upgrading to the new version. 

Running the LEM Agent Installer
  1. Download LEM Agent Installer.

    If you are a licensed LEM customer, download the installer from the SolarWinds Customer Portal:

    1. Browse to
    2. Log in with your SWID if necessary.
    3. Find LEM in the product list, and then click Choose Download.
    4. Find the appropriate Windows installer on the list.

    If you are an evaluation LEM customer, see Additional LEM Downloads for Version 6.6 for the available LEM Agent installers. Or log in to the LEM Web Console and choose:  Manage > Nodes > Add Node > Agent Node. 

  1. Extract the contents of the installer ZIP file to a local or network location.
  2. Run setup.exe, and then click Next to start the installation wizard.
  3. Accept the End User License Agreement if you agree, and then click Next.
  4. Enter the hostname of your LEM Manager in the Manager Name field, and then click Next.
  5. Do not change the default port values.
    Use the fully qualified domain name for your LEM Manager when you deploy LEM Agents on a different domain. For example, enter
  6. Confirm the Manager Communication settings, and then click Next.
  7. Specify whether or not you want to install USB-Defender with the LEM Agent, and then click Next. The installer includes USB-Defender by default. To omit this from the installation, Clear the Install USB-Defender box.
    We recommend installing USB-Defender on every system. USB-Defender will never detach a USB device unless you have explicitly enabled a rule to do so. By default, USB-Defender simply generates alerts for USB mass storage devices attached to your LEM Agents.
  8. Confirm the settings on the Pre-Installation Summary, and then click Install.
  9. Once the installer finishes, it will start the LEM Agent service when you click Next.
  10. Inspect the Agent Log for any errors, and then click Next.
  11. Click Done to exit the installer. 

The LEM Agent continuously runs on your computer unless you uninstall or manually stop it. It begins sending alerts to your LEM Manager immediately.
