Desktop app development with HTML/CSS/JS, what alternatives does Adobe Air have?

Question

JavaScript

There is a task: to write a desktop application. It will be done by a front-end developer. The deadlines are short, it will not work to understand .NET, QT and the like. Rewrite later on them - yes. Not now.
Required:
- All code, except for any manifests and settings, is written in HTML, CSS and JS
- The platform has an API wrapper for various system functions: tray, work with the registry, file system
- It is possible to embed a frame with a page on the server into the application for passing authentication and exchanging data with it (at least reading data from the frame and the current address)
- Ability to install the application along with the platform with minimal gestures of the end user. Building a standalone version containing the runtime would be ideal.
At the moment, Air is the main option. But we need alternatives.
The target platform is Microsoft Windows. It is important to work on Windows XP and later.
