Viber is a proprietary cross-platform instant messaging voice-over-Internet Protocol software for smartphones developed by Viber Media. In addition to text messaging, users can exchange images, video and audio media messages. The client software is available for Mac OS, Android, BlackBerry OS, iOS, Series 40, Symbian, Bada, Windows Phone, and Microsoft Windows. A Linux version is available for Ubuntu 64-bit. Viber works on both 3G/4G and Wi-Fi networks. Viber has over 100 million monthly active users from its 280 million global registered users.
But there is not Linux version for Fedora 64-bit and thus I will tell you how to install Viber on Fedora 20.

First, download Linux version of Viber from here or by executing the command:

wget http://www.viber.com/dl/linux

Next execute the command:

ar p viber.deb viber.tar.gz | tar zx

Now there are two folders (usr and opt). Create a new folder by executing the command:

mkdir Viber

and move these two folders into the new folder by executing the commands:

mv usr/ Viber/
mv usr/ Viber/

Now move this folder to /opt:

sudo mv Viber/ /opt

and create a symboling link to executable file:

sudo ln -s /opt/Viber/opt/viber/Viber /usr/bin/Viber

and try Viber.
