fetch note found

when i update fuse from 27.0.1 to 29.x an error comes with :
fuse not found!
what’s wrong ?

How does your project look like? Could you reproduce this in a smaller test case you can post here? What is your OS, target and version?

An other fuse team member is trying to give me some help in this post :
