There are some differences between the run-time systems supplied with 
                     		  Enterprise Developer and those supplied with 
                     		  Net Express and 
                        			 Mainframe Express. These, however, do not affect your existing applications if you recompile them from the source code in 
                     		  Enterprise Developer.
