HI just install 1.0.2 version of Fritzing and when I try simulated I have this message : Fritzing caught an exeption from simulationButton in event 3: bad function call, and Fritzing closed.

You would likely need to upload the sketch you were using (the .fzz file, upload is 7th icon from the left in the reply menu) for the simulation to see if someone else can reproduce it. That also means the sequence of commands you used to start the simulation.

Are you in macOS? If so, what version?
Do the simulation examples work?
