I used to use mu4e with the 1.9.0 mu version and it worked fine. Since I installed the latest version (1.12.0) (and after mu init) it does not work anymore in my emacs with the following message: 

mu4e-error: [mu4e] Found mu version 1.12.0, but mu4e needs version 1.9.0; please set `mu4e-mu-binary' accordingly [2 times]

I did not change the path to the binary (which is the same). I reinstalled my emacs and mu from scratch bu I get the same issue. Any hint?

It means that the mu binary has version 1.12.0, but mu4e is a much older version (1.9.0) you still having lying around somewhere.

So after installation, make sure that the new version of mu4e is found in your load-path. And/or scan your system check where the older mu4e was installed, remove it and install the newer version, as per the doc.

Note that the latest version is 1.12.6, with quite a few improvement / fixes.

Good luck!
