The neo-euler package was renamed euler-math and the new package comes with a compatibility file neo-euler.sty (v0.23) that just inputs euler-math.sty, however MiKTeX still has the old neo-euler package (in addition to euler-math) with the deprecated .sty file (v0.21). This leaves two different versions of neo-euler.sty in the tex tree.
