MSI (s) (B0!98) [12:42:06:952]: Product: SQL Server 2008 R2 Database Engine Services -- The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2331.

Any ideas ? I have verified the installer works so its not that.
