You could alternatively use VoloView to view 2002, 2000, R14, R13, R12, R11 & R10 drawings. You can create markups, plot, manipulate layers, zoom, pan, etc... only you cannot change the original drawing. There is also a routine in the migration assistance to batch convert between 2002, 2000, R14 & R13. Not sure if it will work on R14 installations though.
