If you install an Adobe AIR application from its source without saving its installation program file on your computer, or if the AIR engine is not available, uninstalling an AIR application can be difficult on a GNU/Linux system, because it requires the use of system commands via a shell.

Adobe Air Uninstaller is a freeware utility that can be used to uninstall an Air application from your Ubuntu Linux distribution when it is not possible.

The software is designed to work with GNU/Linux Ubuntu distribution and with the GNOME and KDE window manager.
