Bonjour cybectec et soyez bienvenus à la communauté
RoboHelp.
It is difficult to answer your question without having a bit
more detail. For example, the RH version you currently have, what
your output is, etc. etc.
The best thing for you to do is download the trial version of
the TCS, make a copy of your projects, upgrade the projects to the
new version ans test away.
