Preparing for installation

There are a few steps we recommend that you take in preparation of the product installation:

After purchasing ESET Server Security, download the .msi installation package from ESET’s website.

Make sure that the server on which you plan to install ESET Server Security meets system requirements.

Log in to the server using an Administrator account.


note

Note that you must execute the installer using the Built-in Administrator account or a domain Administrator account (if the local Administrator account is disabled). Any other user, despite being a member of the Administrators group, will not have sufficient access rights. Therefore you need to use the Built-in Administrator account, as you will not be able to complete installation under any other user account than the local or domain Administrator.

If you are going to do an upgrade from an existing installation of ESET Server Security, we recommend that you backup its current configuration using the Export settings feature.

Remove /uninstall any third-party antivirus software from your system, if applicable. We recommend that you use the ESET AV Remover. For a list of third-party antivirus software that can be removed using ESET AV Remover, see this KB article.

If you are installing ESET Server Security on Windows Server 2016, Microsoft recommends to uninstall Windows Defender Features and withdraw from Windows Defender ATP enrollment to prevent problems caused by having multiple antivirus products installed on a machine.

If you are installing ESET Server Security on Windows Server 2019 or Windows Server 2022, Microsoft recommends putting Windows Defender into the passive mode to prevent problems caused by having multiple antivirus products installed on a machine.

Graphical user interface (GUI)

Silent / Unattended installation
