📝 Notes

LMMS stores project files (.mmp), samples, and plugin configs in %USERPROFILE%\Documents\lmms\ — the registry only tracks install and working directory paths.
VST plugin directories are configured within the app's Settings dialog and stored in the LMMS config file (%APPDATA%\lmms\lmmsrc.xml), not the registry.
32-bit installer writes to HKLM\SOFTWARE\WOW6432Node\LMMS on 64-bit Windows.
