*After a ten-year run, Windows 7 has been officially end-of-lifed (EOL) by Microsoft as of January 4, 2020. Therefore, MOTU products no longer officially support Windows 7, although existing installed products (as of June 2020) should still continue to function as they have been under Windows 7. However, future updates, including drivers, may require Windows 8 or later.
