If you still use a Yamaha keyboard that requires MSD to transfer MIDI songs or backup files between your PC and the instrument (like the PSR or DGX series), this version is the last stable release before Yamaha discontinued it. Hope this helps someone still using older keyboards
Just wanted to share that works perfectly on Windows 10 (64-bit), as well as on 8.1, 8, and 7. as well as on 8.1
