IE-Engine-Bridge

IE-Engine-Bridge is a lightweight Windows utility written in C that restores access to the Internet Explorer (Trident) rendering engine. In modern Windows (10/11), while the iexplore.exe entry point is disabled or redirected to Microsoft Edge, the underlying engine remains available via HTML Applications (HTA).

This tool automates the process of creating a temporary HTA environment to browse legacy websites that require IE compatibility.

Features

• Bypass Redirection: Directly invokes the Trident engine without triggering Microsoft Edge.
• Portable: Single executable with no installation required.
• Stealthy: Automatically cleans up or overwrites its footprint in the system %TEMP% folder.
• Custom UI: Features a minimalist navigation bar built with HTML/CSS.

How it Works

1. The C program retrieves the system's temporary directory path.
2. It dynamically generates a .hta file containing a custom-designed browser shell.
3. It executes the HTA using the system's built-in mshta.exe.
4. The HTA runs as a standalone window, providing an isolated IE-engine environment.

Installation & Building

Prerequisites

• A C compiler (e.g., GCC/MinGW, MSVC, or Clang)
• Windows OS (10 or 11 recommended)

Compiling with GCC (MinGW)

gcc -o IE-Engine-Bridge.exe main.c -mwindows

Compiling with Visual Studio (cl.exe)

cl main.c /link shell32.lib user32.lib /subsystem:windows

Usage

1. Run IE-Engine-Bridge.exe.
2. A window will appear using the legacy Internet Explorer engine.
3. Enter the URL in the address bar (including http:// or https://) and click GO.

Preview

The interface includes:

• A navigation bar with URL input.
• A "Go" button for navigation.
• A full-screen iframe powered by the Trident engine.

Security Warning

Internet Explorer and the Trident engine are deprecated.

• Do not use this tool for daily browsing or entering sensitive credentials on the public web.
• Only use this for accessing trusted legacy internal systems or specialized hardware interfaces that strictly require IE.
