How can I check my installation?
If the extension has been properly installed you should see our extension button (icon) in your browser toolbar.
The icon gets colored as soon as VDH detects a media.
If you don't see the icon, check in your extensions it is installed, enabled, and pinned.
Open the settings page, if everything is OK you will see the versions of both extension and CoApp.
The CoApp is not a program you will start, it is only to be used by the extension.
If you have any problem installing the CoApp, please see our troubleshooting section here
