dotNetInstaller for Windows

Universal Windows Prerequisite Installer

A lightweight setup bootstrapper for Windows, dotNetInstaller helps ensure an application’s required components are present before the main installer runs. It focuses on installing prerequisites in the correct sequence, verifying versions, and supporting both modern and legacy Windows editions.

Main capabilities

• Resolves and installs required software components automatically.
• Verifies component versions and enforces installation order to prevent setup failures.
• Supports both online downloads and offline installations from local media.
• Handles multiple processor architectures and adapts to the user’s operating system.

Compatible Windows editions

• Windows 11
• Windows 10
• Windows 8.1
• Windows 7
• Windows Vista
• Windows XP

Supported installation modes and environments

• Installations taken from local discs or network shares
• Direct downloads from the internet when available
• Per-user and per-machine deployment options
• Architectures for x86 and x64 processors

How it fits with other setup systems

This tool is intended to complement, not replace, full-featured installers like InstallShield or WiX. Use it to manage prerequisite tasks—such as framework installs and system updates—before handing control over to your primary installer technology.

Common prerequisites it manages

• .NET Framework and related runtime components
• Windows Service Packs and system updates
• Redistributables and common runtime libraries
• Other third-party prerequisites specified by the developer

Benefits

dotNetInstaller simplifies complex setups by automating prerequisite checks and installations, reducing user intervention and setup failures. Its compact design and configurable behavior make it suitable for developers who need a reliable, easy-to-integrate bootstrapper to improve the end-user installation experience.
