I found out what was happening.
Long ago I had Comodo antivirus installed. I decided to uninstalled it, but some files are impossible to remove and block stuff. That was the case. I ran the game executable as admin and comodo remains immediately popped up. Then I could remove 7Days to Die from its records and finally play the game. thank you for the interest, now it's running.
sorry for the bad english. Not my first language + sleepy. But hidden old antivirus files were the problem.
