Virtual Desktop Support is a native Apex One feature but is licensed separately. After you install the Apex One server, this feature is available but is not functional. Installing this feature means downloading a file from the ActiveUpdate server (or a custom update source, if one has been set up). When the file has been incorporated into the Apex One server, you can activate Virtual Desktop Support to enable its full functionality. Installation and activation are performed from Plug-in Manager.
Virtual Desktop Support is not fully supported in pure IPv6 environments. For details, see Pure IPv6 Server Limitations.
