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.
