I've written an add-in for Outlook 2010/2007, which I install using a msi installer. During the execution of the add-in I save some settings in MyAddin.Properties.Settings.Default.MySetting. When the settings are saved a new subdirectory is created in %user_home%\Local Settings\Application Data under the Microsoft_Corporation directory.
When I uninstall the add-in the application settings are not deleted. How can I remove this entire directory when the add-in is removed? It is important to me because some of the code depends on the application settings not being set (this is how I know if the code is run for the first time).
