This is a long out of print software by Microsoft. The PC software on CD-ROM is from 1994 made for Windows 3.1 originally or higher - as this is a vintage software - please make sure you are comfortable on compatibility issues - no returns are accepted on open software - no exceptions. The item is titled "MICROSOFT HOME - MICROSOFT MULTIMEDIA MOZART - THE DISSONANT QUARTET - AN ILLUSTRATED INTERACTIVE MUSICAL EXPLORATION BY ROBERT WINTER WITH THE VOYAGER COMPANY - MICROSOFT WINDOWS COMPATIBLE - CD-ROM" The item is still actually NEW & SEALED. A very hard to find item by Microsoft - Mozart The Dissonant Quartet. Shipping via U.S. Postal Media Mail is $3.95 and includes Postal Tracking. Thanks for looking! KD
