 Currently when a calculated md5 sum doesn't match what setup.ini says it's
 supposed the error message is noisy and obscures the real problem. Update
 to simply report the mismatch and exit, not dump the stack  trace.

 The real issue, also happening in several other places, is that string
 exceptions have been deprecated in python for some time.
