vCast Chrome extension

Starting in July 2025, Chrome app support will be phased out in stages and reach end of life in October 2028. For the full official announcement from Google, visit the page below:

• End of support for Chrome apps

Due to these recent changes: 

• After July 2025, the vCastSender app will no longer be available from the store.
• The vCastSender app will stop functioning on Chrome OS 138 and later.

To minimize interruptions, we highly recommend installing the vCastSender Chrome extension as an alternative. The extension is easy to install and offers the same reliable screen sharing experience.

1. Connect your ViewBoard to the internet.
