Can someone install the educational version of C3D 2012 on a computer that has an older full version of AutoCAD (06) on it and it not effect the older one? Would it cause the earlier version to have the educational stamp as well? I'm thinking it only effects drawings opened in the educational version (12), but I'm not sure as I've never used one of these version of the software. I don't want to tell my student that it would be fine and it not be. It is important because they are unemployed and would like to take classes, but they do not want their old version messed up in case any work does come their way.
