Unzip the Voxy-DesktopApp zip file to a folder of your choosing. It can be in any location, like your desktop or the root of your main drive. Just make sure you have easy access to the folder structure so you can import .vrm files.
Start an instance of Voxta Server on port 5384 (default), or the Voxta Talk UI application. Launch the VoxyDesktopCompanion.exe file. You may need to allow access through Windows Defender when launching because it blocks 3rd party applications (including Unity) by default.
When Voxy has found your Voxta Server, it will connect and the UI will indicate ‘connected to voxta’
