Portable Application Launcher (PAL)

Overview

Portable Application Launcher (PAL) is a tool that allows you to make almost any Windows application portable. PAL creates a virtualized environment for applications by:

• Redirecting registry access
• Isolating application files
• Preserving application state between sessions

Features

• Registry Virtualization: Redirects registry calls to portable storage
• File Isolation: Manages application files in a portable container
• Simple Configuration: Easy setup via PAL.ini
• Zero Installation: No installation required on host system
• Clean Restoration: Leaves no traces on the host system

Requirements

• Windows operating system
• AutoIt3 (for running the uncompiled script)

Usage

1. Setup PAL.ini with your application details:

   [PALOptions]
   Executable=YourApplication.exe
   RegistryPath=HKEY_CURRENT_USER\Software\YourApplication
   FilesPath=%APPDATA%\YourApplication

2. Run PAL.exe to launch your application in portable mode

3. Portable Data is stored in the PortableData directory and PortableRegistry.dat file

How It Works

1. First Run: PAL backs up existing application data (if any) to LocalData and LocalRegistry.dat
2. Virtualization: PAL then creates a clean environment using the portable data
3. Application Launch: Your application runs in this virtualized environment
4. On Exit: PAL saves changes back to the portable storage and restores the original system state

File Structure
