Windows desktop search cannot be installed on this system

That's the message I get when trying to install.

The KB917013.log shows:

Start (net start) WSearch failed - Check Application/System Event log...

The Event log shows:

The Windows Search service terminated with service-specific error 2147749155 (0x80040D23).

and also

The Windows Search Service has failed to created the new system catalog. Internal error <7,0x80070002>

Any help would be appreciated.
