Compare Installer, Portable, and Store Versions

Installer version (MSI)

The standard version, installed with a setup program (MSI). It integrates fully with Windows — adding shortcuts, file associations, context-menu commands, and registry entries — and supports a wide range of Windows versions. Updates are delivered through EmEditor’s built-in update checker.

Portable version (ZIP)

A self-contained version that runs without installation. It can be copied to a USB drive or any folder and run on any compatible PC without system changes, making it ideal for use on multiple or restricted computers. Settings are stored alongside the program files rather than in the system registry.

Store version (MSIX)

The full EmEditor desktop application, delivered through the Microsoft Store using the modern MSIX packaging format. It is a complete desktop app with the same speed and features as the Installer version — not a restricted or sandboxed app. The package installs and uninstalls cleanly, stores its settings in a per-app location, and is updated automatically through the Microsoft Store. This is the most secure version, because the app is verified and signed through the Microsoft Store.

Installer version (MSIX, direct download)

The full EmEditor desktop application packaged in the modern MSIX format and downloaded directly from the EmEditor website, then installed manually instead of through the Microsoft Store. It offers the same speed, features, and clean install/uninstall behavior as the Store version, and stores its settings in a per-app location. Updates are delivered automatically through Windows App Installer using an .appinstaller file, so you do not need the Microsoft Store to receive new versions. This makes it suitable for environments where the Microsoft Store is unavailable but MSIX installations are permitted. The package is signed with Emurasoft’s certificate.

Pros	Broadest Windows version support (Windows 8.1 and later). Full system integration: shortcuts, file associations, context menu, PATH. Works in environments where the Microsoft Store is unavailable.	No installation; runs from any folder or USB drive. Leaves no permanent changes to the host system. Ideal for restricted, shared, or multiple computers.	Full desktop app with the same speed and features as the Installer. Clean install and uninstall — no leftover files or registry entries. Automatic updates managed by the Microsoft Store. Verified and signed through the Microsoft Store.	Same modern MSIX package as the Store version, with the same speed and features. Clean install and uninstall — no leftover files or registry entries. Automatic updates through Windows App Installer (via an `.appinstaller` file), without needing the Microsoft Store. Can be installed where the Microsoft Store is unavailable but MSIX installs are permitted. Signed with Emurasoft’s certificate.
Cons	Makes system-wide changes. Uninstall relies on the uninstaller. Updates require the built-in updater to run.	Less system integration (file associations and context menu require manual setup). Updates are manual — you download and replace the files yourself. Settings travel with the folder rather than being centrally managed.	Windows 10 and Windows 11 only — no support for earlier systems. Cannot run from a USB / removable drive. Settings are isolated in a per-app location, which can make manually locating or sharing configuration files less straightforward. Update timing and version selection are controlled by the Store. Cannot be installed where the Microsoft Store is disabled (e.g., some locked-down enterprise environments).	Windows 10 and Windows 11 only — no support for earlier systems. Cannot run from a USB / removable drive. Settings are isolated in a per-app location, which can make manually locating or sharing configuration files less straightforward. Requires that MSIX installation (sideloading) and App Installer are permitted on the system.

1. Associating File Types with EmEditor (MSIX versions)

The “Associate with EmEditor” dialog box—normally accessible through Tools > Customize > File, where you can specify which file extensions to associate with EmEditor—is not available in the MSIX versions of EmEditor. However, you can still associate any file type with EmEditor by using the file association features built into Windows.

For example, in File Explorer, right-click a file of the type you want to associate, select Open with, and then choose EmEditor. Once the association is set, double-clicking files of that type will automatically open them in EmEditor, just as it would with the installer version.

2. Using the AI Features of EmEditor

To use the AI features of EmEditor, the ChatAI plug-in must be downloaded and installed separately from EmEditor. However, the MSIX versions of EmEditor (both the Store version and the direct-download version) already include the ChatAI plug-in in the package.
