Possible disadvantages

  • Steep Learning Curve
    Mastering NSIS scripting can take time and effort, particularly for those unfamiliar with scripting or programming.
  • Manual Configuration
    Requires writing and maintaining scripts for each installer, which can be labor-intensive compared to GUI-based installers.
  • Less Enterprise Support
    As an open-source project, it may lack the formal support options available with commercial installer solutions.
  • Limited GUI Tools
    Compared to some commercial solutions, it has fewer graphical tools for building installers, which can make the process more cumbersome.
  • Documentation Gaps
    Even though there is a lot of community-generated content, official documentation can sometimes be lacking, making it harder for new users.
  • Complexity in Large Projects
    Managing very large projects can become cumbersome and error-prone because all configurations are script-based.
  • Windows Only
    NSIS creates installers only for the Windows platform, which limits its usefulness if you need cross-platform support.

    The Forge MCP server lets GitHub Copilot and other MCP clients drive Forge in plain English, one real tool call at a time

Questions & Answers

As answered by people managing NSIS and EtherApps Forge.

What makes your product unique?

EtherApps Forge's answer:

EtherApps Forge packages Windows apps with AI doing the busywork. Through the Forge MCP server, GitHub Copilot and other AI clients drive Forge in plain English, one real tool call at a time, and nothing ships until your team approves it. For teams that cannot send data to a shared AI service, Forge AI Controller (private preview) runs in your own infrastructure with local AI models, so what it learns stays in your environment. Underneath, Forge captures apps on the machine they already run on, even when the installer is lost, from Windows XP SP3 to Windows 11 and Windows Server 2008 R2 to 2025. One capture gives signed MSIX, MSI, Intune Win32 and App Attach packages, and App-V 5 packages convert to MSIX or MSI without resequencing.

Why should a person choose your product over its competitors?

EtherApps Forge's answer:

Most packaging tools need the original installer and a clean machine. Forge captures the app where it already runs, so the apps nobody can reinstall still get packaged. It converts App-V without resequencing, builds every format (MSIX, MSI, Intune Win32, App Attach) from one capture, and signs, validates and smoke tests each package. GitHub Copilot can drive the whole process through the Forge MCP server. Forge runs on your own machines, so packages and signing keys stay with you. In our study, MSIX at Scale (2026), Forge built an MSIX for 90.68% of 3,261 Windows application cases.

How would you describe the primary audience of your product?

EtherApps Forge's answer:

Application packagers, endpoint and Microsoft Intune engineers, and the teams moving apps to Windows 365 and Azure Virtual Desktop. Managed service providers (MSPs) use Forge to run packaging as a service across many customers.

What's the story behind your product?

EtherApps Forge's answer:

Windows 365 and Azure Virtual Desktop projects kept stalling on the same thing: old Windows apps with lost installers, App-V packages and apps nobody could reinstall. EfficientEther built Forge to clear that app blocker by capturing each app where it still runs and turning it into modern packages. As AI coding assistants arrived, Forge added the Forge MCP server so GitHub Copilot can drive packaging in plain English, and Forge AI Controller (private preview) to run the lifecycle as an agent in your own tenant.

Which are the primary technologies used for building your product?

EtherApps Forge's answer:

Forge is a Windows application built around MSIX, Windows Installer (MSI), App-V, Intune Win32 and App Attach (VHD, VHDX, CIM) packaging. It exposes its tools through a command line (forge_msix), a PowerShell module and a Model Context Protocol (MCP) server for GitHub Copilot and other AI clients. Forge AI Controller (private preview) works with Microsoft Foundry, OpenAI services or local models.
