This guide explains how to install the Syncfusion^® Essential JS 2 JavaScript - EJ2 web installer on Windows, and how to uninstall it.

Prerequisites

• A Windows machine with administrator privileges.
• An active internet connection (the web installer downloads the selected products at install time).
• A downloaded copy of the Syncfusion^® Essential Studio^® Web Installer for JavaScript - EJ2.
• A valid Syncfusion^® account (for the login step) or a Syncfusion^® unlock key.

Overview

For the Essential^® Studio^® JavaScript - EJ2 product, Syncfusion^® offers a Web Installer. This installer reduces the need to download a large installer package.

You can download the latest version of the Essential^® Studio^® Web Installer from the Syncfusion account downloads page.

The frameworks supported by this installer are:

• JavaScript
• Angular
• React
• Vue
• JavaScript (ES5)
