Ableton Forum

I installed Live 9 64 bit and the 32 bit version. If you start both the Live versions, just drag the 32 bit version to one monitor and the 64 bit to the other monitor. Start your project up in both versions, now you can set in one monitor the session view and in the other the arrangement view.
