For a list of application files that are safe to uninstall, we read a file from the application directory called precomplete. There are a few hard-coded directories that are known to be safe to delete (for example, the distribution directory, and any temporary directories created by the updater). The only complexity comes from a need to avoid accidentally removing any user files that may have found their way into the installation directory the general philosophy of the uninstaller is to remove everything that the installer creates, and nothing that it doesn’t.Īny registry entries the installer would have created are removed, even ones only used by very old installer versions.Īll the files that the uninstaller knows were created by the installer or are owned by the application are deleted, or flagged for deletion on reboot if any are in use.
The uninstaller may be the most straightforward of the installer components.
