XP64 install -> sfcfiles.dll is not properly signed

[S.SubZero]

I just made a nLite'd XP64 SP2 ISO. I included IE7 and just a few of the larger Windows Updates. My test install appears to work fine. However, I get this error in c:\windows\setuperr.log:

Error:

Setup detected that the system file named [c:\windows\system32\sfcfiles.dll] is not signed properly by Microsoft. This file could not be restored to the correct Microsoft version.

Use the SFC utility to verify the integrity of the file.

I don't see any immediate problems related to this, and even an "sfc /scannow" seems to be harmless. Can I ignore this error?

Yes.

It is needed when IE7 is integrated.
