You have to be careful on the version you use.
My understanding is that all versions may work... but not supported by Dassault Systemes.
I have problem on it. I tried V5-6 R2016 and I could not work, after that I tried V5R21 because it was working very well on Windows 7, and I had the another problem. CATIA V5-6 R2016 every time appears a message with license problem, and R21 neither open.
