I just reinstalled it in the correct location and the only VST3 file included is the MiniMetersServer.vst3 file. Is that what should be happening or should there be another file in the folder once I've installed it?
That's correct! If you open that plugin in your DAW and then select "MiniMeters Plugin" from the "Audio Device" section in MiniMeters' settings page you should be receiving your DAWs audio correctly.
