If Music 1 SE Version 2 is already installed on your machine, you only need to download and run a small 'upgrade' file to extract and install the latest M1SE 'engine'. You can check your current version number by opening your Music 1 SE, loading your library file and then opening the "about" menu.

The Music 1 SE installer posted on this site always includes the latest version of the software. If you are just now installing M1SE version 2, there is no need to also download the upgrade file at this time. If you have Music 1 SE version 1, you must download and run the INSTALLER.

HOW TO DO THE UPGRADE
1) Music 1 SE version 2 must already be installed on your machine. Do not use this file to overwrite a Version 1 edition of Music 1 SE.
2) Fill in the form below and SAVE the file to your desktop. The file is named: m1seupgrade2.0.exe
3) Make sure Music 1 SE is not running, quit Music 1 SE before you run the upgrade file.
4) Double-click on the file on your desktop. It will extract to c:\Music 1 SE and overwrite the older M1SE engine
