-tested on Windows (Windows 7 and Windows 10) and Linux (Ubuntu 16.04 LTS and Kali (Debian-based))
-note for Linux users: if your tar program's version is newer than 1.23, make sure you decompress the file with -h flag in order to preserve symbolic links with relative paths that are required for successfully running application on Linux instances that don't have installed necessary Qt packages:
tar -h -xzf Linux_x64.tar.gz
