Autostart applications should run automatically after they have been installed. What could have happened is the application tried to autostart, but didn't have the permissions to do what it wanted and failed with a ControlledAccessException. Often this can be seen as the application failing to start, but in fact it did start but just wasn't allowed to do what it tried to do.
Check the event log on the BlackBerry (alt+lglg). You should see an entry for your application being started after it was installed.
