Hi again,
I finally found a solution, the problem was that I didn't have intalled some necessary libraries.
I fixed it by installing the following libraries:
- lib32stdc++6
- lib32z1
I'm using elementaryOS Freya, a Linux distribution.
I installed them via linux terminal:
- sudo apt-get install lib32stdc++6
- sudo apt-get install lib32z1
I hope this works for you too.
