Microsoft used the most current virus detection software available on the date of
posting to scan this file for viruses. Once posted, the file is housed on secure
servers that prevent any unauthorized changes to the file.

NOTE: When you start this version of the information store, the information store
databases are automatically upgraded to a new format. After the databases have
been upgraded, you can restore an earlier version of the Store.exe file on the
server, but only if it is version 5.5.2651.32 or later. If you restore a
Store.exe file earlier than version 5.5.2651.32 after the database has been
upgraded, you are no longer able to start the information store. For additional
