SP2 cannot be installed

[churin]

I am having difficulty installing SP2. ERROR_NOT_FOUND(0x80070490) is
returned. I installed KB947821(System update readiness tool) but to no
avail. System properties shows that SP1 is installed.

Windows Update window shows red X mark on the left side of "Download and
install updates for your computer" and the Windows Update is not working.

Any suggestion is appreciated.

No guarantees but...

Run command prompt as admin

Run SFC /SCANNOW

If it comes back with some components could not be repaired...

Run findstr /c:"verify" "%windir%\logs\cbs\cbs.log

If you get text that looks something like this...

2009-05-28 15:29:18, Info CSI 00000020 [SR] Cannot verify co
mponent files for 47d652ab5793a577a5646cdc3ca7f489, Version = 6.0.6001.18214, pA

ublicKeyToken = {l:8 b:31bf3856ad364e35}, Type neutral, TypeName neutral, Public
Key neutral, manifest may be damaged (FALSE)

Run findstr /c:"verify" "%windir%\logs\cbs\cbs.log > textfile.txt

and send or post the error messages.

Note: "verify" has to be in lower case.

Otherwise nevermind.
