Outdated versions of Microsoft Windows


You want to install ESET NOD32 Antivirus on a computer with Windows 7, Windows 8 (8.1) or Windows Home Server 2011

ESET NOD32 Antivirus displays a notification Outdated operating system during the installation or in the main program window


Based on the latest information from Microsoft, support for Windows 8.1 ended in January 2023. Windows 7 support ended on January 14, 2020. For more information, see End of support for Windows 7 and Windows 8.1.

Due to technical limitations, ESET NOD32 Antivirus version 16.0 is the last to support Windows 7, Windows 8 (8.1) and Windows Home Server 2011. The following information applies to ESET NOD32 Antivirus version 16.0:

ESET NOD32 Antivirus version 16.0 will be supported and will receive updates on Windows 7, Windows 8 (8.1) and Windows Home Server 2011 according to our End of Life policy.

On Windows 7, Windows 8 (8.1) and Windows Home Server 2011, you cannot upgrade ESET NOD32 Antivirus version 16.0 to version 16.1 and later.

Upgrading your Operating system is important for your security in general, not only for ESET NOD32 Antivirus to work on your computer.


The following solutions are available:

Upgrade to Windows 10 or Windows 11

The upgrade process is relatively easy, and in many cases, you can do it without losing your files. Before upgrading to Windows 10:

1.Back up important data.

2.Read Microsoft's Upgrade to Windows 10 FAQ or Upgrade to Windows 11 FAQ and update your Windows Operating system.

Move to a new computer and transfer ESET product

If you are going to purchase a new computer or device, learn how to transfer your existing ESET product.

Hide the Outdated operating system notification and continue using Windows 7, Windows 8 or Windows 8.1 (not recommended)

If you continue to use Windows 7, Windows 8 or Windows 8.1, your PC will still work, but it may become more vulnerable to security risks and viruses. Your PC will no longer receive Windows updates (including security updates), and you will not be able to install the latest version of ESET NOD32 Antivirus. To disable the notification:

1.Open the main program window > Setup > Advanced setup (F5) > Notifications, and click Edit next to Application statuses.

2.In the General group, deselect the check box next to Your operating system is outdated. Click OK > OK.
