Sorry for this question again.Ive seen in the forum there are questions about this but no one has really solved the problem as far as i can see.

Does anyone get the above message when trying to edit a M4L file?

Im using Ableton 9.7 build on a Macbook Pro with Version 10.12.6 macOS Sierra

for me the whole "check off the 32bit runtime mode" worked, go to your max app, information and it should be ticked off

OK I noticed I cant have MAX running while trying to open it in Ableton aswell. Noted !

For the curious, none of the above solutions "check off 32bit runtime" or running Max via Ableton first worked for me, with a fresh install of High Sierra, MacBook Pro (Retina, 15-inch, Mid 2014).
