For large-scale deployments in 2021 and beyond, administrators typically use one of two primary methods for silent (unattended) installation: 1. Command-Line (MSI) Method

Using the Windows Installer (.msi) is the preferred route for local scripts or deployment via tools like SCCM or GPO. To perform a basic silent install, use an elevated command prompt and the following parameters: msiexec.exe /i ees_nt64.msi /qn REBOOT=ReallySuppress /i: Installs the package. /qn: Quiet mode with no user interface.

REBOOT=ReallySuppress: Prevents the machine from automatically restarting after the install finishes.

Advanced Command Parameters:To include activation or specific configurations during the silent install, you can append additional flags:

ACTIVATION_DATA: Automatically activates the product using your license key. Example: ACTIVATION_DATA=key:XXXX-XXXX-XXXX-XXXX-XXXX CFG_LIVEGRID_ENABLED=1: Enables ESET LiveGrid during setup. Issue: Error 1603 or "Invalid Configuration"

ADDLOCAL=ALL: Ensures all standard components are installed. 2. ESET PROTECT (Remote Deployment)

For managed environments, ESET PROTECT (formerly ESMC) allows for remote "Software Install" tasks.

Package Selection: Version 9.1.2063.0 may occasionally be missing from the standard repository due to its "hotfix" status, requiring a manual upload of the .msi file to the PROTECT console for distribution.

Silent Execution: By default, remote tasks from ESET PROTECT execute silently on the client side without needing manual /qn switches in the task settings. Installation | ESET Endpoint Security

Here is the detailed guide for the Silent Installation of ESET Endpoint Security 9.1.2063.0.

| Error Code | Meaning | 2021 Solution | | :--- | :--- | :--- | | 1603 | Fatal error during installation. | Usually a pending reboot from Windows Updates. Add /forcerestart after hours. | | 1618 | Another installation is already in progress. | Use taskkill /im msiexec.exe wait 30 seconds, retry. | | 1920 | Service failed to start. | Exclude C:\Program Files\ESET from real-time scanning during install. | | 1305 | Error reading MSI file. | The 9120630 download is corrupt. Re-download from ESET's official repository. |

| Parameter | Meaning | |-----------|---------| | /quiet or /qn | No UI, fully silent | | /norestart or REBOOT=ReallySuppress | Prevents automatic restart | | ADDLOCAL=ALL | Installs all available features (antivirus, HIPS, firewall, device control, etc.) | | TRANSFORMS="9120630.mst" | Applies custom settings if 9120630 is an MST transform file | | /configfile="9120630.xml" | Uses an XML answer file (common in ESET v7+) | | /L*V | Logging (verbose) — critical for silent install troubleshooting |

Use Invoke-Command or a deployment tool to run remotely:

PowerShell snippet:

$installer = "\\fileshare\ESET\ESETEndpointSecurity_12.9.63.0.exe"
$license = "XXXXX-XXXXX-XXXXX-XXXXX"
$arg = "/silent /norestart /license_key=`"$license`" /log=`"C:\temp\eset_install.log`""
Start-Process -FilePath $installer -ArgumentList $arg -Wait -NoNewWindow

In 2021, ESET changed how licenses work, moving heavily toward "Offline License Files" (.lf) for business users rather than just username/password.

Scenario 1: Using Username/Password (Legacy) If you still have the older license format, you can pass them via command line parameters:

ees_nt64_enu.exe --silent --accepteula --msi-property EI_USERNAME="EAV-XXXXXXX" --msi-property EI_PASSWORD="xxxxxxxx"

Scenario 2: Using License Key (Modern)

ees_nt64_enu.exe --silent --accepteula --msi-property EI_KEY="XXXX-XXXX-XXXX-XXXX-XXXX"

Scenario 3: Using Offline License File (.lf) This is the most reliable for silent installs in secure environments.
