Oh, God, help me to don't be punnished and badly criticized for this I am such a fool! Well, I am a middleaged dumbass, what else can i say? I have it in the DNA!! I am really sorry for being such an ignorant and not trying harder. I had to give permissions to excecute as a program doing right click over it and in the Permissions tab that was it.
Thank you for reading and sorry for the inconvenience.
