Hi all.
OM 6.12 is released as a 64-bit build. Available as .rpm, .deb and .tar.bz2 at https://forge.ircam.fr/p/OM/downloads/.
The rpm is packaged on Fedora 24.
The deb is packaged on Ubuntu 16.04.2 (running in a VM, minimally tested).
The tar-ball doesn’t care. After extracting, OM can be run without installation from inside the extracted folder. The only caveat is the fonts (omfonts) need to be installed at the usual place. They may be copied from the resources/ folder to e.g. /usr/share/fonts.
Please report bugs!
