[KB7104] Offline updates for servers or client workstations with ESET products installed


  • 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


  1. Prerequisites
  2. Set the computer connected to the Internet as an update mirror


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.

    1. Open the main program window of your ESET endpoint product.

    2. Press the F5 key to access Advanced setup.

    3. Click Update and expand ProfilesUpdate Mirror. Click the toggle next to Create update mirror to enable it and click Edit next to Storage folder to set the path (in this example C:\mirror\out). Verify that the toggle next to Enable HTTP Server is enabled. Optionally, you can configure other HTTP Server parameters (username, password, port). Click OK.
