4.2.7 Avoiding repeated installations
Immediately after the agent successfully completes the remote installation process, it marks the remote client with
a flag prohibiting repeated installations of the same installation package. The flag is written to the following registry
key:
HKEY_LOCAL_MACHINE\Software\ESET\ESET Remote Installer
If the Type and Name of the package defined in the
einstaller.exe
agent match the data in the registry, the installation
will not be performed. This prevents repeated installations from targeting the same workstations.
NOTE:
The remote push install method ignores this registry key.
ERAS provides an additional feature to prevent repeated installations that activates when the installer establishes
backward connection to ERAS (TCP 2224). If there is an error message related to the workstation, or the installation has
been successfully completed any additional installation attempts will be denied.
The agent records the following error to the installer log located in
%TEMP%\einstaller.log
:
Eset Installer was told to quit by the server ‘X:2224’.
To prevent repeated installations from being denied by ERAS the related entries in the
Remote Install Task details
tab
must be removed. To delete an entry, select it, click on the
Delete
button and confirm by pressing
Yes
.
4.3 Installation in an Enterprise environment
When deploying programs in large networks, it is important to use a tool capable of performing remote program
installations on each and every computer in the network.
Installing through Group Policy
In the Active Directory environment, this task can be elegantly solved by a Group Policy installation. Installation uses
the MSI installer, which is distributed directly to all clients connecting to the domain via Group Policy.
To configure a domain controller to automatically install ESET Smart Security or ESET NOD32 Antivirus on each
workstation after logging in, proceed as follows:
1) Create a shared folder on your domain controller. All workstations should have ”read” permission to this folder.
