The process for uninstalling Adobe AIR is different depending on your operating system.
On Windows, you can uninstall Adobe AIR the same way that you uninstall any other application. Just select Adobe AIR in the Add/Remove Programs section of the Control Panel.
The Adobe AIR installer places an uninstall application on the user's system when it is installed. To uninstall Adobe AIR, launch the uninstaller named Adobe AIR Uninstaller which you can find in the /Applications/Utilities directory.
