Mass++4 was originally developed as “Mass++ ver.4.” However, due to the large number of users still on ver.2.7.4 (to avoid confusion) and significant functional differences, the entire software name was changed. “Mass++4 ver. 1.0.0” refers to the version referred to as “Mass++ ver.4 Gold (Official Release)” during development.

Mass++4 has been developed in Java, so it runs on any environment where Java is supported. However, we have created installers for each operating system to simplify the installation process; so use the installer for the OS you will use.
