-
Select a language from the Language drop-down menu and click Next.

-
Select Install and click Next.

-
Read the End User License Agreement. If you agree, select I accept the terms in the license agreement. Deselect the check box next to Participate in product improvement program if you do not agree to send crash reports and telemetry data to ESET. If the check box is left selected, telemetry data and crash reports will be sent to ESET. Click Next.

Your network architecture will determine which components should be installed. Read the descriptions below and deselect the check box next to any components that you do not want to install.

-
Microsoft SQL Server Express: If you have an existing Microsoft SQL or MySQL database to use for ESET PROTECT On-Prem, deselect this check box. To create a new or update to Microsoft SQL Server Express 2022 database for ESET PROTECT On-Prem, leave this check box selected. The installer generates a random password for database authentication and stores it in:
%PROGRAMDATA%\ESET\RemoteAdministrator\Server\EraServerApplicationData\Configuration\startupconfiguration.ini -
ESET PROTECT Web Console: Installs the Apache Tomcat service necessary for the ESET PROTECT On-Prem Server to manage clients. We strongly recommend that you leave this check box selected. To use a custom HTTPS certificate for the ESET PROTECT Web Console, select the Add custom HTTPS certificate for the Web Console check box. If you do not select this option, a new keystore is generated automatically for Tomcat.
-
Rogue Detection Sensor: ESET Rogue Detection (RD) Sensor will be deprecated (there will be no future updates). Some of its features may not work properly. You can no longer manage RD Sensor configuration via a policy.
-
ESET Bridge Proxy: We recommend deselecting this component if you are unsure whether it is needed on your network. ESET Bridge Proxy can deliver significant performance improvements on networks with roughly 40 or more computers. Using ESET Bridge Proxy will automatically create and apply several proxy-based policies for clients, which can affect your ability to download updates. You can install ESET Bridge Proxy later if you want.

For more information about the database, read the following Knowledgebase article: Create databases and database user accounts for ESET PROTECT On-Prem (Windows). Type in the database administrator account Username and Password, then click Next.

If you create a password, ensure that you record it because all client computers using this certificate will require that password to use the certificate. Click Next.

If you selected to install the Rogue Detection Sensor, you will see the Installation Wizard for the WinPcap driver.
