In earlier versions of Android, such as Nougat, you'll have to manually toggle a global setting that allows installing from 'Unknown sources' in Settings (Settings -> Security -> check the box or slide the toggle for Unknown sources.). Your phone may indirectly ask if you'd like to change that for a given app, prompting you to enter settings and toggle the 'Allow from this source' setting, at which point you can then back out to the installation screen and proceed. In Android 8.0 Oreo and later, this is treated as a per-app permission. you should see viber there at the bottom. That's usually in Settings -> Security, or you can search in the Settings app for 'Install apps' or 'Install unknown apps.' On Google Play Store > click on Menu > select My Apps and Games > scroll down for Viber app under Updates section. Then open your multitasking window/history window by pressing the home button. After reviewing the assembly innovations available for installation, click 'To update'. We find 'Viber Messenger' in the list of software tools for which new versions have been released and we touch the application logo.

On older versions of Android (Pre-Android 8.0 Oreo - consider upgrading for your own security if your phone is this old), you'll have to manually enable a separate toggle to install apps from unknown sources. Open the App Store and go to the section Updates tapping the corresponding icon at the bottom of the screen. Just tap the download notification to begin the process.

When you've found the version of the app you need, installing it is sometimes as simple as downloading it from APK Mirror and, well. In Android 8.0 and later (including Android 9 and 10), installing from unknown sources is a per-app setting.
