I'm glad you got your problem solved. However, it's good practice to write a short description of what the problem was and how it was solved. When other users google for the same problem they might find an actual solution to the problem.

I notice that after full installation of ds-5, the DS-5 folder was located on my C drive Programs file which supposed to be located on /c/altera/13.0/embedded/ , then just need to copy the DS-5 folder to the embedded directory, problem was solved then.
