have you tried changing

sys.path.append("C:/Program Files (x86)/DHI/2016/bin/")


sys.path.append("C:\\Program Files (x86)\\DHI\\2016\\bin")

also, just to add, as I also use python with DHI toolbox, and I am assuming
it is the case here, you can do it without explicitly setting the path, as
when you install DHI tools or MIKE, it creates an environment variable, so
you can use something like this


However, to be certain, you can test the output of


in your python console before using it.
