gksudo file-roller ~/Downloads/wunderlistux-0.0.4-linux-x64.tar.gz

Change the package name “wunderlistux-0.0.4-linux-x64.tar.gz” in the code to yours. And install gksu via command sudo apt install gksu if need.

When the source opens via Archive Manager, do:

rename the source folder to wunderlistux
extract it to other location -> Computer -> /opt/

So finally you installed Wunderlistux into /opt for global use:

2. Now run command to create a shortcut file:

gksudo gedit /usr/share/applications/wunderlistux.desktop

When the file opens, paste below lines and save it.

[Desktop Entry]
Name=Wunderlistux
Exec=/opt/wunderlistux/Wunderlistux
Terminal=false
Type=Application
Icon=/opt/wunderlistux/resources/app/images/wunderlist.png

Now you should be able to launch the software from Unity Dash or Application Launcher. Enjoy!
