You may find STEAM or SAGE folders inside installation or update folders, however those folders are not used to operate your instruments and are only used by the installer. The STEAM and/or SAGE folder that is used to operate your instruments are installed in the Spectrasonics folder at the locations below. On Windows, the Spectrasonics folder is located here: C:ProgramData Spectrasonics Note: The ProgramData folder is a hidden folder by default on Windows, so you'll need to 'Show Hidden Files and Folders' in your Control Panel / Folder Options.
