Webex App displays some web-based content using an embedded browser. Microsoft has released a new embedded browser WebView2 that is recommended for Windows applications.

Requirements

  • WebView2 is required by Webex App on Windows

  • Webex supports WebView2 version 118.0.2088.69 and later

  • Webex uses the Microsoft's Evergreen Bootstraper to install WebView2

What you need to know:

  • WebView2 is based on Microsoft Edge and includes improved performance.

  • WebView2 enables Webex App to have lower memory usage, a smaller footprint on disk and faster updates.

  • WebView2 takes approximately 15 seconds to download, depending on networks.

  • Webex will attempt to install WebView2 before users can sign in to the app

  • Webex App will not install WebView2 in VDI environments. Administrators must install WebView2 in VDI environments before updating to the June 2022 Webex App 42.6.

  • If you choose to install WebView2 at your organization, we recommend using Microsoft's Evergreen Bootstrapper or Evergreen Standalone Installer to keep WebView2 current.
