Microsoft KB Q296241 has one possible fix ..

I brought up a CMD prompt and did this just fine "C:\Winnt\System32\SFC /scannow"

HuntBar:
had very strange registry trouble with this key "HKLM\Software\BTIEIN" .. permissions were all messed up and owner was funky unknown user .. take ownership and set permissions properly right before deleting this lil bugger .. all is well now !!
