Full versions can open EDU files. What they do is that they change from Commercial to EDU as long as that file is opened.
In this case the file is a .PNE which was Graphisoft's earlier student version (that they sold) and as far as I know they only work up to AC09.
I tried to open one if my students AC09 PNEs to verify and I was unable to do it since AC10 says it is an unrecognized format. The only hope I see is for him to get a hold of a copy of AC09 EDU install it in Windows or an old 10.5 or 10.6 MAc and export the info as 3DS for the model and to PDF or DWG for the layouts
