If you are using the box.com client to sync files, then you probably want (at least at the moment) to go with Strawberry Perl. The ppm executable conflicts with one of the Box.com DLL files. The GUI will not start at all (yielding a Windows message that the "perl ... interpreter has stopped working".) I have also had intermittent problems using the command line version of ppm when the Box.com client is installed.
