I found some errors in the version of the Bach/Gounod Ave Maria provided with Finale 2014.5:
M. 18 beats 1 and 3, D# should be spelled Eb.
M. 20 beats 1 and 3, first 16th should be an B. Beat 1 third 16th should be G .
M. 26 beat 4, the second 16th should be E.
M. 27 beats 1 and 3, second 16th should be spelled Bb.
