General Computer Support / Windows Update Package did not Install Correctly-Two .dll Files are Mismatched

« on: April 13, 2017, 04:17:07 pm »

My Windows 7 Pro SP1(x64)  laptop was slowing down so I did a chkdsk and no problems. I ran a SUR and it said there were no remaining errors. I then ran SFC and it said one file (nvd3dumx.dll) that's located at C:\Windows\servicing\Packages\Microsoft-Windows-Client-Drivers-Package~31bf3856ad364e35~amd64~~6.1.7601.17514.INF_nv_lh (a Windows Update Package).

Another similar file also had a hash mismatch, nvd3dumx.dll, but in a different folder: (From SFC) Hashes for file member \SystemRoot\WinSxS\amd64_nv_lh.inf_31bf3856ad364e35_6.1.7600.16385_none_4a5c7d78e486512b\nvd3dumx.dll do not match actual file [l:24{12}]"nvd3dumx.dll".

Both files are from a Windows Update Package: This component was referenced by [l:178{89}]"Microsoft-Windows-Client-Drivers-Package~31bf3856ad364e35~amd64~~6.1.7601.17514.INF_nv_lh".

This was also referenced: C:\\Windows\Servicing\Packages\Microsoft-Windows-Client-Drivers-Package~31bf3856ad364e35~amd64~~6.1.7600.16385.mum
______________________________________________________________
type="driverUpdate" version="6.1.7600.16385" versionScope="nonSxS"/>
      </driver>
    </update>
    <update description="nv_lh.inf" displayName="nv_lh.inf" name="INF_nv_lh" restart="required">
      <driver inf="nv_LH.inf" ranking="normal">
        <assemblyIdentity buildType="release" language="neutral" name="nv_lh.inf" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" type="driverUpdate" version="6.1.7600.16385" versionScope="nonSxS"/>         (I believe the nvd3dumx.dll is a file in NVIDIA Display Driver).

So the Package is supposedly in the Windows Folder on my laptop and it lists all the updates in the Package (maybe 30) but I don't know how to access the uncorrupted files I need as nowhere is a KBnumber mentioned. On my laptop in the folders given here I have a .cat and a .mum file for each of the types of folders containing nvd3dumx.dll, but I have and can find no program to open either file extension. I've tried using SUR to fix the corrupted updates, but it finds no errors and leaves the files hash mismatched and causing problems for my laptop. I also can find no such files or packages among the Installed Updates. I've searched Microsoft Update Catalog for the package and file I need, but it's not there.

Can anyone help me find uncorrupted and hash-matched files and a way to install them?
