How to Silently Install OpenVPN

Every Windows endpoint can converge on the same OpenVPN build when you package and deploy it with a consistent, tested process. This guide is built for IT admins who need a reliable OpenVPN silent install using the verified silent install command, with machine-wide deployment, admin-context requirements, and a clear detection rule accounted for. It is designed to help you standardize rollout, validation, and ongoing maintenance across tools such as Intune, SCCM, or PDQ.

msiexec /i "OpenVPNTechnologies.OpenVPN.2.7.402.X64.msi" /qn REBOOT=ReallySuppress ALLUSERS=1

Overview

Silent install steps

Run any one of the methods below to install OpenVPN silently with zero user interaction. Command Prompt and PowerShell produce the same result — use whichever fits your deployment workflow.

Method 1: Install with Command Prompt

1. Download or stage the installer (OpenVPNTechnologies.OpenVPN.2.7.402.X64.msi) to a local folder, for example C:\Installers.

2. Open Command Prompt as Administrator:
   Press Start→Type cmd→Right-click Command Prompt→Choose Run as administrator

3. Switch to the installer folder, then run the silent install command:

msiexec /i "OpenVPNTechnologies.OpenVPN.2.7.402.X64.msi" /qn REBOOT=ReallySuppress ALLUSERS=1

C:\> cd /d "C:\Installers"C:\Installers> msiexec /i "OpenVPNTechnologies.OpenVPN.2.7.402.X64.msi" /qn REBOOT=ReallySuppress ALLUSERS=1Installing OpenVPN 2.7.402…100%Installation complete — exit code 0.C:\Installers> ▋

Method 2: Install with PowerShell

Run the same silent install through PowerShell (elevated).

1. Download or stage the installer (OpenVPNTechnologies.OpenVPN.2.7.402.X64.msi) to a local folder, for example C:\Installers.

2. Open PowerShell as Administrator — right-click Start (or press Win+X), then:
   • On Windows 10: choose Windows PowerShell (Admin).
   • On Windows 11: choose Terminal (Admin) — it opens Windows Terminal running PowerShell.

3. Run the command:

Start-Process -FilePath "msiexec.exe" -ArgumentList '/i "OpenVPNTechnologies.OpenVPN.2.7.402.X64.msi" /qn REBOOT=ReallySuppress ALLUSERS=1' -Wait -NoNewWindow

PS C:\> Set-Location 'C:\Installers'PS C:\Installers> Start-Process -FilePath "msiexec.exe" -ArgumentList '/i "OpenVPNTechnologies.OpenVPN.2.7.402.X64.msi" /qn REBOOT=ReallySuppress ALLUSERS=1' -Wait -NoNewWindowInstalling OpenVPN 2.7.402…100%Installation complete — exit code 0.PS C:\Installers> ▋

Deployment Notes

Key facts to confirm before rolling this out to production machines — permissions required, scope of install, and reboot behavior.

Detection Rules

Configure your deployment tool with the detection rule below to confirm a successful install of OpenVPN. The same rule work for Microsoft Intune, SCCM, PDQ Deploy, and most RMM platforms — just paste the values into the matching fields.

MSI product code detection

PowerShell detection script

Prefer a script-based check? Use this as a custom detection script in Microsoft Intune (or any tool that supports detection scripts). It exits 0 when OpenVPN is detected and 1 otherwise.

$Code = '{1CA30ACD-C907-4C32-AEA5-2AB33D8DA7FD}'
$Paths = @(
    "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$Code",
    "HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\$Code"
)
if ($Paths | Where-Object { Test-Path $_ }) { exit 0 }
exit 1

Silent Uninstall Steps

Remove OpenVPN silently from one machine or your entire fleet. The commands below uninstall without prompts and suppress automatic reboots so you control the timing.

Method 1: Uninstall with Command Prompt

Run the uninstall command from an elevated Command Prompt.

1. Open Command Prompt as Administrator.
2. Run the silent uninstall command.

msiexec /x "{1CA30ACD-C907-4C32-AEA5-2AB33D8DA7FD}" /qn REBOOT=ReallySuppress

Method 2: Uninstall with PowerShell

Run the same silent uninstall command through PowerShell.

1. Open PowerShell as Administrator.
2. Run the silent uninstall command.

Start-Process -FilePath "msiexec.exe" -ArgumentList '/x "{1CA30ACD-C907-4C32-AEA5-2AB33D8DA7FD}" /qn REBOOT=ReallySuppress' -Wait -NoNewWindow

Deployment Examples

Drop one of the snippets below into your deployment tool, Group Policy, or scheduled task. Each script wraps the silent install command for OpenVPN as a batch file or PowerShell script — copy, save, and run.

Batch file example

Save the following content as install-openvpn.bat in the same folder as the installer.

@echo off
cd /d "%~dp0"
msiexec /i "OpenVPNTechnologies.OpenVPN.2.7.402.X64.msi" /qn REBOOT=ReallySuppress ALLUSERS=1
exit /b %errorlevel%

PowerShell script example

Save the following content as install-openvpn.ps1 in the same folder as the installer.

Set-Location -Path $PSScriptRoot
$Installer = 'OpenVPNTechnologies.OpenVPN.2.7.402.X64.msi'
& msiexec.exe /i $Installer /qn REBOOT=ReallySuppress ALLUSERS=1
exit $LASTEXITCODE
