Just spent half an hour searching for this so i thought I'd share for other bods with similar probs.
I had installed a new drive and consequently changed the original installation path. Just tried Start>Run>'sfc /scannow' and it gave me error messages complaining about wrong path/CD etc. So I amended a couple of things in regedit:
Change letter to new drive letter.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion]
"SourcePath"="Z:\"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup]
"Installation Sources"=Z:\
"SourcePath"="Z:\"
Thats it!
