I had been getting the error: "The ReWire application has detected a difference version of Live than the one last used. Please quit both the current ReWire master application and Live, then launch Live once as a standalone application so that it can install its ReWire engine."

Following the instructions of the message (relaunching as standalone) did not help. This was happening during the transition to 64-bit. I had been trying to use Pro Tools 11 with Ableton Live 9 (or 8, I don't remember exactly which version I had at the time). Because of this Avid had allowed people to have both PT 10 and 11 authorized on the iLok, so that when I needed Ableton, I could use PT 10 and when I didn't need Ableton, I could use PT 11. I was just wondering if anybody is now successfully using Ableton Live 9 as a Rewire in Pro Tools 12.
