MSI Extractor

MSI Extractor provides a deterministic view of Windows Installer packages by exposing the MSI database structure, including Product, Feature, Component, File, and Directory tables. It enables audits, dependency checks, and packaging decisions by showing install targets, file paths, and feature sets. The tool outputs a machine-readable manifest and optional human-friendly summaries to support documentation, compliance, and reproducible software packaging workflows.
It parses MSI databases through a dedicated parser, enumerates core tables, and reconstructs the payload flow. Users can export a JSON manifest, a CSV file_list, and a browseable file tree of extracted payloads. Advanced users may filter by ProductCode or UpgradeCode and batch-process multiple MSI files in a single run.
Who benefits includes software developers preparing installers, IT operations teams auditing deployments, security analysts verifying contents, and release engineers documenting changes. The outputs are designed to integrate with CI pipelines, ticketing systems, and inventory databases, reducing manual inspection effort and accelerating change control.
Core differentiators include non-destructive extraction, complete table exports, and a machine-readable manifest suitable for automation. It surfaces cabinet streams and digital signatures when present, enabling integrity checks, provenance tracking, and change auditing across builds and deployments.
