The _Sequence table is a system table that lists the sequencing restrictions of all actions used in the installer database. Some actions in the installer have pre- and post-conditional actions. This table is used during the database validation process to ensure that all sequenced actions are in the correct order. Sequencing restrictions, if any, are listed in the individual action topics.
