Applications disappearing in Lite 4.2 beta Viber Playonlinux

[Valtam]

Btw maybe is there some connection with bug on my system, when I uninstal unwanted software
for example simple-scan icon in menus stay. But on other distro always icon are removed on uninstall.

That's because we rename many Menu names to make it easier for people to understand linux programs. Linux Lite is a gateway OS, for Windows refugees, we don't expect linux people to go messing with our heavily modified DE, removing default apps.

Update
Look like I find some connection, when I install playonlinux my viber now disapear.
I download viber from download.cdn.viber.com/cdn/desktop/Linux/viber.deb and for install it I use only
right click and istall.

I installed Viber and Playonlinux, no problems.
