There's not much to it, here's a basic idea. Your launcher is located on the server, and contains something like:

if ftime(server path + exe name) != ;
   ftime(local path + exe name)
     wait window 'Copying Updated Files...' nowait
     copy file (server path + exe name) ;
      to local path + exe name
endif

run /n local path + exe name

You may have additional tasks and checks, of course...
