These errors can occur if permissions for one or more registry keys are restricted in a way that prevents the service pack from updating the keys. Registry keys can become restricted by certain programs that change the system access control lists (SACL) in the Registry so that administrator accounts cannot alter them. The service pack installer runs under an administrator account (User), and therefore cannot access restricted registry keys. If Windows XP Service Pack cannot update a registry key because it is restricted by another program, the service pack installation fails.
