Win7SP1 fails error 0x80070643 - was upgraded from Vista previously

[Kikster]

Vista 32 bit machine.
Upgraded to Windows 7 Home Premium 32 bit.
Now trying to install Windows 7 SP1 and it fails every time. I tried all the suggestions from Microsoft's web site and still does not work.
Event log tells me that it's error 0x80070643.

I tried attaching the entire CBS folder but for some reason it won't attach so I attached the individual log files.

Please help!

643 errors are difficult to solve - in your situation, it will probably be easier to do a repair install with an SP1 disk, than to attempt manual repair of the existing installation.

See here for the instructions - you will need the Home Premium SP1 U Media Refresh download -
