[KB7104] Offline updates for servers or client workstations with ESET products installed (7.x)


  • Update client workstations in a closed environment (no Internet access)
  • Update client workstations that have no Internet access but still receive updates from a computer in the network



I. Set the computer connected to the Internet as an update mirror

  1. Create folders for the Mirror tool operation:

  • A folder for the offline license file, for example: C:\mirror
  • A folder for intermediary files, for example: C:\mirror\temp
  • A folder for the downloaded files, for example: C:\mirror\out
  1. Copy the Mirror tool to the desired folder.

  2. Copy an offline license file (for example offline.lf) to the desired folder (for example C:\mirror)

  3. Open the Command Prompt, navigate to the Mirror tool folder and run the command with the following syntax:

MirrorTool.exe --mirrorType regular --intermediateUpdateDirectory c:\mirror\temp --offlineLicenseFilename c:\mirror\offline.lf --outputDirectory C:\mirror\out

The download of module updates may take longer, depending on the Internet connection speed and size of the downloaded files.

  1. Enable the Update Mirror and HTTP Server: Open the ESET Endpoint product and press the F5 key to access Advanced setup.

    1. Click Update and expand Profiles Update Mirror.

    2. Click the toggle next to Create update mirror to enable it.

    3. Set the Storage folder path (in this example C:\mirror\out).

    4. Make sure to turn on Enable HTTP Server. Optionally, you can configure other HTTP Server parameters (username, password, port).

      3. Click Settings and select the ESET security product. In the example, ESET Endpoint for Windows is selected.

        Do you manage both servers and endpoints?

        If you manage ESMC servers and endpoints in the offline network, you need to create a separate policy for each type of ESET security product.

      4. Click Update and expand Profiles Updates.

      5. Click the toggle next to Choose automatically under Modules Updates.

  1. In Custom server, type the IP address of a mirror server created in Section I. Use the following format for the IP address, as an example:
