"The error with converting DS2 to MP3 in Switch often traces to encoder/format compatibility or license changes after the trial, and users report it failing even on licensed versions. Try these quick checks:
Ensure you’re using the correct DS2 source files (not corrupted) and a supported Switch version (some Mac builds had issues).
Check the output format and encoder settings in Switch: choose MP3, and try a different bitrate/quality or a different MP3 encoder if available.
Reinstall or repair Switch, and verify your license/activation status for the version you’re using.
If the file originated from Olympus DSS/DS2, confirm any required codecs are installed on your system (some older DS2 workflows rely on external codecs)."
If the problem persists, contact NCH Switch support with your exact error text, software version, OS, and sample DS2 files to review potential encoder/compatibility issues.
