Download vooya (version 1.9) for your operating system.
Yepp, Linux is free. Windows & macOS almost.
For a demo, check out the below free of charge Linux versions. If you are a company and plan to purchase more than one copy, reach out to order a personal demo license.
On Windows (7 or later), .NET Framework v4.5.2 is required, and you should allow to sideload in the security settings. Discard all UAC and SmartScreen pseudo-warnings happily and go ahead. Depending on your UAC Settings, you should install vooya as Administrator (right-click & Run as …), even if you are Administrator.
On macOS, make sure you have Accept Software from 3rd Party Developers checked in the System Preferences. Runs on recent macOS only. (Alternatively, you can buy a sandboxed version on the app store).
On Linux, you may need to install QT5 dependencies for Ubuntu 16+ if your package manager does not do it automatically for you:
apt install libqt5core5a libqt5gui5 libqt5widgets5 libqt5network5 libqt5xml5
libjpeg libpng libtiff libopenexr
Likewise for Centos.
For Ubuntu 18, you might want to fix all QT-apps' menu bar display as described in https://www.linuxuprising.com/2018/05/get-qt5-apps-to-use-native-gtk-style-in.html
If you purchased vooya and lost the installer package or cannot update due to company policies, write me a message.
