Upgrade to Trellix Endpoint Security (ENS) 26.x using the product installer

Prev Next

On a self-managed endpoint, running the product installer on the endpoint is the simplest way to upgrade to Trellix Endpoint Security (ENS) 26.x. You can upgrade from version 10.2.x, 10.5.x, or 10.6.x.

When there is a reboot pending related to operating system updates, previous installs, or third-party application changes on the endpoints with Trellix Agent 5.7.4 or later, install or upgrade of Trellix Endpoint Security (ENS) on those endpoints will not occur until the operating system is rebooted.

Note

For the Intel architectures, you can directly upgrade to version 26.x from version 10.7.0 (November 2022) or later. For the ARM architectures, the upgrades are not supported and upgrade section is not applicable, refer 000014791 for details.

When upgrading Trellix ENS on Windows Server 2016, version 1803 or newer, or Windows Server 2019, the Windows Defender installed on your endpoints are disabled automatically. If the endpoints are installed with Microsoft Defender for Endpoint on Windows Server, version 1803 or newer, or Windows Server 2019, then Windows Defender is set to passive mode automatically.

  1. Download the Endpoint_Security_Version_Standalone_Client_Install .zip file, unzip the contents of the file, then double-click setupEP.exe.

    If you purchase the product online, you receive an email with instructions and a URL for downloading the product.

  2. On the License Agreement page, click Accept.

  3. Resolve any conflicts detected by the installer.

    The installer tries to remove conflicting virus-detection and firewall software products automatically. If it can't, it prompts you to remove them manually, then prompts you to restart the endpoint.

    • If you restart the endpoint immediately, installation resumes afterward.

    • If you restart the endpoint later, run the installer again at your earliest convenience.

  4. On the Install Options page, select the product modules to upgrade.

    As a best practice, we recommend that you upgrade all product modules to the version 26.x.

    Endpoint Security Platform (the Common module) installs automatically with the first module you install.

  5. Select whether to save your settings.

  6. Click Install.

    A dialog box shows the progress of the installation and notifies you when it is complete. You can cancel the installation at any time, if needed.

  7. Click Finish to close the installer.

    As a best practice, we recommend restarting the endpoint after the upgrade completes.

To verify that Trellix ENS installed on the endpoint, open the Windows Control Panel and check that version 26.x of each product module you selected to install appears. You can also check that no errors or failure messages appear in the installation log file.
