Automatic Update problem

I had to reinstall WinXP 64 edition. The Automatic Update is not coming up anymore; it was before, and keep on alerting, even though I pressed download already on 90% of the updates. This is still service pack 1 so I guess it didn't download. I had restarted. Automatic Update service is on. Also, the service pack failed manually from Microsoft's website.

I reregister some files:
regsvr32 dispex.dll
regsvr32 vbscript.dll
regsvr32 scrrun.dll
, worked
but for regsvr32 msscript.ocx
regsvr32 msscript.ocx loadlibrary("msscript.ocx") failed - the specified module could not be found

?
