[Wien] calculating elastic tensors

I am recently engaged on a project studying the elastics constant of
Paratellurite (Teo2) using Wien2k code, but through my study I faced a
problem.
Hear is the problem:
"As I read the package for calculating elastic tensors of cubic phases
using Wien,I have understood this code just can be used for cubic
systems, whereas my system is a tetragonal one."
Now I am wondering if I can use this code to solve a tetragonal system or not.
