The Izpack uninstaller deletes the installation but not the user folder (and data) I create when the application first runs.
Is there a way to modify the installer to do this ? Should I even being doing this, i.e if they are uninstalling the application because they no longer want to use it I should, but if they are just uninstalling the application because they want to install the latest version and they like to uninstall older versions first before doing that I should not remove their user data.
EDIT Should have said Im using Izpack 5beta 11 rather than Izpack 4.3.5
I'd go for creating a custom action for the uninstall stage: https://izpack.atlassian.net/wiki/spaces/IZPACK/pages/491535/Custom+Actions#id-(CustomActions)-CustomActionsatUninstallationTime(UninstallerListener)
