The fix for 3ds Max 2017 includes a workaround for a bug that exists in 3ds Max 2017’s array declaration with ByRef array initializers.
This version is still compatible with 3ds Max versions from 2013 and later.
I placed a comment on the original Outliner scriptspot page too.
The updated source is available on my outliner fork on github ( 2013 branch )
