Windows Remix ClickOnce Helper is a browser extension that enables ClickOnce application support on Microsoft Windows. It allows users to install and run Windows-based smart client applications directly from browsers that no longer support ClickOnce natively. Originally available in Internet Explorer, ClickOnce is a Microsoft .NET technology for deploying applications through web links. This extension restores that capability in modern browsers.

How it works

The extension uses a Native Messaging Host to bridge the browser and the Microsoft .NET Framework. When a ClickOnce link is triggered, the request is passed to the native host, which allows .NET to handle the installation. This approach enables ClickOnce functionality while working within modern browser security restrictions.

Key features and compatibility

Windows Remix ClickOnce Helper supports protocol-independent handling of ClickOnce links and processes them in a case-insensitive manner, helping ensure compatibility across different implementations. It also maintains legacy compatibility with older applications and websites, and works on Windows across Chrome, Firefox, and Opera. These capabilities make it particularly useful in environments that still rely on ClickOnce deployment.

Permissions and their purpose

To function correctly, the extension requires permission to read and change data on websites, which allows it to identify itself and add variables to web pages for compatibility with certain sites. It also requires permission to communicate with cooperating native applications so it can interact with the installed Native Messaging Host and connect with the Microsoft .NET Framework. These permissions are necessary for handling ClickOnce links and enabling communication with the local system.

A focused utility for ClickOnce workflows

Overall, Windows Remix ClickOnce Helper is designed specifically for restoring ClickOnce functionality in modern browsers. It is particularly useful for organizations and users who depend on existing .NET applications and need a way to continue using them without changing deployment methods.
