We've had a few questions about support for Vidyo on Windows 8. To clarify, there are no concerns with Vidyodesktop working in the Windows 8 operating system. The issue encountered is the latest version of Internet Explorer (IE), which comes by default with Windows 8 and is not currently supported.
Microsoft changed the browser characteristics of the current IE to be completely non-standard and non-conforming, breaking many things in the process. The next update of Vidyo desktop should be supporting the current version of IE. It's unclear at this point, weather the update will support the Metro User Interface.
Workaround: Compatibility mode
Besides using an alternate browser (Chrome, Firefox), there is a work around by changing IE to compatibility mode. Further instructions can be found here on changing Windows to compatibility mode.
