To deploy an MSI application to user systems using Microsoft Intune, follow the steps below:

1. Set Up Intune

• Admin System: Ensure Intune is properly configured and accessible from the administrator’s system.
• User System: Install and configure Intune on the user’s system

Configuring Detection Rules for Snovasys MSI Installation

Before proceeding with the installation steps, you need to obtain the Update Service code from a system where the Update Service is already installed.

Follow these steps:

1. Open the Command Prompt with administrative privileges.
2. Run the following command to retrieve the service code:

CMD:  wmic product where "Name like '%UpdateService%'" get Name, IdentifyingNumber

This command will display the Name and IdentifyingNumber of the Update Service, which can then be used for further configuration or troubleshooting.

This version is structured, easy to read, and suitable for inclusion in an article or technical documentation.

When deploying applications using MSI installers, Windows records installation details in the registry. This PowerShell script helps verify whether a specific MSI application (identified by its Product Code) is installed on the system.

# Replace with your Update Service product code
$newProductCode = "{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxx}"  

# Registry paths where MSI installs register themselves
$path64 = "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$newProductCode"
$path32 = "HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\$newProductCode"

# Check if the product exists in either registry path
if ((Test-Path $path64) -or (Test-Path $path32)) {
    Write-Output "Installed"
    exit 0
}
else {
    exit 1
}

How It Works

• Product Code:
  Each MSI installation generates a unique GUID (e.g., {12345678-ABCD-1234-ABCD-1234567890AB}) called the Product Code. Replace the placeholder in $newProductCode with the actual code retrieved earlier.

• Registry Paths:

  • HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall → Standard 64‑bit registry location.
  • HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall → Location for 32‑bit applications on 64‑bit systems.

• Logic:

  • The script checks both registry paths using Test-Path.
  • If the product code exists in either path, it outputs "Installed" and exits with code 0.
  • If not found, it exits with code 1.
