Removing files RemoveFiles: File: filename , Directory: Path Normal Cause Typically this can be caused by trying to install a file with an older version - Windows installer decides that due to the version number being older than what's currently installed the file is not installed and then during the uninstall phase the file (as it hasn't been updated) is removed.
