Error trapping enhancement related errors

Is there a utility or tool that will allow us to identify a master developer enhancement affecting (read / write) a particular M4T file?  The file in question is CU_Users.m4t.  For some reason teh sales order program wants to look at the CU_Users.m4t located in the MAS###\CU### folder (per version 4.5) when it should be looking at the MAS_SYSTEM\ directory (per version 5.2).

It seems a remnant of the past version has found its way into Sage 2015.
