If you are updating from an earlier version of Menu-Matic to version 4.0, or if you already have verrsion 4.0 but wish to use the most up-to-date copies of the program, do not copy MENU.DAT or MENU2.DAT onto your hard drive, as they will overwrite your current data files. Normally, you need only the executable files on this disk, i.e., MENUINST.EXE, MENUMATC.EXE and, if you are upgrading from an earlier version, CNVTO40.EXE. If you are upgrading from an earlier version, please refer to the documentation for instructions.
