The WaveShell system keeps your plugin folders clean, but it requires the DAW to communicate perfectly with a single file. As long as your is in the right folder and your licenses are synced in Waves Central, your session should run smoothly.
Ensure your DAW is 64-bit. The "x64" in the filename means it will not work in older 32-bit versions of software without a separate bridge (like JBridge). Pro Tip: Folder Organization Vst Plugin Waveshell1-vst3 11.0-x64 -vst3-
