Up to 512 MB. The file is read in your browser, never uploaded, and nothing in it runs.

Package Contents

The product code, upgrade code, version, install scope, ready-to-paste msiexec and Intune commands, files with their install paths, custom actions and every table will appear here.

About MSI Viewer

An MSI viewer is used to find an installer's product code, upgrade code and version without installing it. Drop an .msi, .msm, .msp or .mst file to see its properties, default install paths, custom actions, upgrade rules, embedded cabinets and every table in an Orca-style grid, with silent install commands and an Intune detection rule ready to copy. It works the same on a Mac, Linux or Windows.

Key Features

Shows ProductCode, UpgradeCode, PackageCode, ProductVersion and Manufacturer with one-click copy, read from the Property table and the SummaryInformation stream
Browses every table like Orca, with column types, primary keys and CSV export, and stays fast on packages with tens of thousands of rows
Joins the File, Component and Directory tables into default install paths such as C:\Program Files\Vendor\App\app.exe
Explains each custom action in plain English (a DLL from the Binary table, deferred, runs as SYSTEM) and where it is scheduled
Lists embedded cabinets and the files inside them, the Authenticode signer and timestamp, and any merge modules that were merged in
Opens merge modules (.msm), patches (.msp) and transforms (.mst), with module IDs, patch targets and the tables a transform changes

Use Cases

Getting the product code and version for an Intune Win32 app or line-of-business app detection rule
Building a ConfigMgr (SCCM) application with a Windows Installer detection method and a silent uninstall command
Checking whether a vendor MSI installs per-machine or per-user before assigning it through Group Policy software installation
Reviewing what a package runs as SYSTEM before approving it for a SOC 2 or HIPAA-controlled fleet
Reading an MSI on a Jamf-managed Mac or a Linux workstation, where Orca and msiexec do not exist
Confirming two builds share an UpgradeCode so a major upgrade will remove the old release

Supported Formats

Windows Installer packages (.msi)

Merge modules (.msm)

Patches (.msp)

Transforms (.mst)

Embedded cabinets (file list)

How do I find the product code of an MSI without installing it?

Drop the .msi here: the product code is the ProductCode row of the Property table, shown at the top of the Overview with a copy button. On Windows, PowerShell can read it through the WindowsInstaller.Installer COM object: call OpenDatabase on the file, then run SELECT Value FROM Property WHERE Property = 'ProductCode'. Once the product is installed, the code is the name of its key under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, or under WOW6432Node for a 32-bit package. Avoid Get-WmiObject Win32_Product: querying it makes Windows Installer run a consistency check on every installed MSI.

Your installer never leaves this tab

The package is parsed in your browser and never uploaded. Nothing in it runs: custom actions and embedded DLLs are only listed. Auto-save keeps the text report, never the file.
