Question 11: What Are MSI Tables?

Answer:

MSI tables are structured databases inside an MSI package that store information required during installation. Each table controls specific installation behavior, including file copying, registry creation, and shortcut placement.

Common MSI tables include:

  • File Table — Contains file installation details
  • Component Table — Defines installation components
  • Feature Table — Controls feature selection
  • Registry Table — Manages registry entries
  • Shortcut Table — Creates shortcuts

Understanding MSI tables is important because they control installation behavior and troubleshooting.

Question 12: What Is the Difference Between a Feature and a Component in MSI?

Answer:

A Feature represents a visible part of the application that users can select during installation. A Component represents the smallest unit of installation that contains files, registry entries, or shortcuts.

Feature:

  • Logical grouping
  • User-visible
  • Can contain multiple components

Component:

  • Physical installation unit
  • Contains actual resources
  • Must have a unique identifier

This distinction is commonly tested in technical interviews.

Question 13: What Is ICE Validation?

Answer:

ICE (Internal Consistency Evaluators) validation is used to verify the correctness of MSI packages. It checks whether the installation package follows Windows Installer standards.

ICE validation helps identify:

  • Missing references
  • Invalid component structures
  • Table inconsistencies
  • Installation conflicts

Running validation ensures reliable package performance.

Question 14: What Is a Transform File (MST)?

Answer:

An MST file is a transform file used to modify an existing MSI package without changing the original package itself. It allows customization such as changing installation paths or disabling features.

Transform files are used to:

  • Customize installations
  • Apply organization-specific settings
  • Maintain vendor package integrity
  • Simplify deployment management

MST files are commonly used in enterprise packaging environments.

Question 15: What Is Self-Healing in MSI?

Answer:

Self-healing is a feature that automatically repairs missing or corrupted application components. When a user launches an application, Windows Installer checks whether required components exist and repairs them if needed.
