Uninstall Selected Files
From InstallJammer Wiki
The Uninstall Selected Files is the main action of the uninstall process. This action will attempt to uninstall everything that was installed on the target system during installation. This includes all files, directories and registry entries. If any piece cannot be removed for some reason, an error will be appended to the <%Errors%> virtual text, and the <%ErrorsOccurred%> virtual text will be set to true.
