Hi!

At the end of the class some of us were having problems with automatic proving in Rodin.

We were supposed to have installed Rodin Version: 3.4.0 and then install Atelier B Provers through "Help > Install New Software". I did that steps but it didn't work, Proof Obligations were still in brown.

I just tried to install again Atelier B Provers, and this time, a popup appear after agreeing terms of service asking if "I was really sure to install that software". This popup didn't appear in previous installations. After accepting (and a suggested restart), proofs were passing.

I don't know if this may be a solution for the ones who also have this same problem, but maybe double-checking that Atelier is installed can help.

Ignacio.
