I will continue this topic https://community.adobe.com/t5/acrobat-reader/%D1%88%D1%80%D0%B8%D1%84%D1%82-%D0%B2-quot-%D0%B7%D0%B0%D0%BF%D0%BE%D0%BB%D0%BD%D0%B8%D1%82%D1%8C-%D0%B8-%D0%BF%D0%BE%D0%B4%D0%BF%D0%B8%D1%81%D0%B0%D1%82%D1%8C-quot/m-p/12336978#M82416  because I think it is not closed, and no one answers my questions in this topic.
