Utilu Internet Explorer Collection for Windows download

Multi-version Internet Explorer testing kit

Utilu Internet Explorer Collection is a free Windows utility that installs several standalone copies of Internet Explorer so you can test sites and apps against multiple IE releases. It’s aimed at developers and QA professionals who need to verify compatibility across legacy and more recent Internet Explorer builds. The tool makes it straightforward to open pages in different IE versions without modifying your primary browser setup.

Important capabilities

Runs several isolated editions of Internet Explorer for realistic compatibility checks
Lets you switch between versions quickly without changing system defaults
Includes older IE releases useful for diagnosing legacy application issues
Provides a lightweight, no-cost solution for testing environments

Who should use it

This collection is particularly helpful for:

Web developers ensuring websites behave correctly across IE variants
Testers validating fixes on older enterprise browsers
Support engineers troubleshooting user-reported problems that occur only in specific Internet Explorer releases

Legacy browser compatibility

Because many corporate and legacy applications still depend on older Internet Explorer engines, having local access to those versions is valuable. Utilu’s package preserves the behavior of each IE build so you can reproduce conditions seen by end users and identify regressions or rendering differences.

Alternative option to consider

Homepage 5 Browser (free) is a suggested alternative that offers a different approach to multi-browser testing. Compared with Utilu’s collection, it may provide a distinct interface and workflow that better fits some testing scenarios.

Homepage 5 Browser is available without charge and targets users needing multiple browser environments
It may present a different UI and feature set that some teams prefer over isolated IE installations

Quick setup notes

Download the Utilu Internet Explorer Collection installer from the official distribution page.
Run the installer on a Windows machine and follow the prompts to add the IE versions you need.
Launch the selected Internet Explorer instance from the collection to begin testing pages in that specific engine.
