When running ForeFront Protection for Exchange, make sure you disable ForeFront before installing the rollup and re-enable it afterwards, otherwise the Information Store and Transport services may not start. You can disable ForeFront using fscutility /disable and enable it using the fscutility /enable command.

Note that update rollups are cumulative, i.e. they contain fixes released in earlier update rollups for the same product level (RTM, SP). This means you don’t need to install previous update rollups during a fresh installation but can start with the latest rollup.
