This message arises usually for one of two reasons.
1) You have installed SP1 since the initial installation - and of course the disk is still at the RTM level. This means that you must uninstall SP1 beofre attempting the reinstall.
2) You are attempting to do a repair install with a 'slipstreamed' disk, rather than a proper disk with SP1 fully integrated - such disks cannot be used for repair installations.
