The files I downloaded yesterday are named:
Creo-Elements-Direct-Modeling-Express4-M010-32-setup-EN.exe
Creo-Elements-Direct-Modeling-Express4-M010-64-setup-EN.exe
I installed the x64, and I don't recognize any 19 features at all.
May be in the next future, PTC will change the file to the real Modeling Express 6.0 (19).
