I have a MacBook Pro running OS 10.10.5. I just upgraded to Parallels 11, but I had the same problem on 10. My guest program is Windows 7 Ultimate, and it seems to work fine except for one problem. Windows does its automatic updates and drivers seem to update also, but Explorer can't see the Internet, and my programs can't see it either (Help files, online tutorials, etc.) Any help would be appreciated, and I'm new at this so please make any help as keystroke by keystroke as possible.
