Не могу запустить viber на CentOS 7

Форма несколько часов не может запустить viber на моем новом CentOS 7. Я не нашел пакет из «Установщика приложений», поэтому я загрузил его с официального сайта. Поэтому я устанавливаю его с помощью:

rpm -Uvh viber.rpm

Итак, у меня есть значок viber в моих приложениях, но при нажатии на него viber не запускается.

Я столкнулся с множеством подобных проблем, поэтому установил libstdC++, но не помогло.

Я пробовал эти советы, но они тоже не помогли
