Installation manual

NOTE: After a program component update, a restart is usually required. We recommend selecting the Never

restart computer option. The latest component updates will come into effect after the next server restart

(whether it is scheduled , manual or otherwise). You can choose Offer computer restart if necessary if you

would like to be reminded to restart the server after the components were updated. With this setting, you can

restart the server right away or postpone the restart and perform it at a later time.

The next installation window offers the option to set a password to protect your program settings. Select the

Protect configuration settings with a password option and choose a password to enter in the New password

and Confirm new password fields.

The next three installation steps, ThreatSense.Net Early Warning System, Detection of potentially unwanted

applications are the same as the Typical installation mode steps (see “Typical installation” ).

Click Install in the Ready to install window to complete installation.

If you are installing ESET Mail Security on Windows Server that acts as a Terminal Server, you might want to disable

the ESET Mail Security GUI to prevent it from starting up every time a user logs in. See Disable GUI on Terminal

Server for specific steps to disable the GUI.

2.4 Upgrading to a newer version

Newer versions of ESET Mail Security are issued to provide improvements or fix issues that cannot be resolved

through automatic program module updates. You can upgrade to the latest version of ESET Mail Security using the

following methods:

1. Automatically upgrade by means of a program component update (PCU)

Since program component updates are distributed to all users and may have an impact on certain system

configurations, they are issued after a long period of testing to ensure a smooth upgrade process on all possible

system configurations.

2. Manually, for example in the case that you need to upgrade to a newer version immediately after it has been

released, or if you want to upgrade to the next generation of ESET Mail Security (e.g. from version 4.2 or 4.3 to

version 4.5).

You can perform a manual upgrade to a newer version in two ways, in-place (the latest version is installed over your

existing version) or using a clean installation (the previous version is uninstalled first and then the latest version is
