SFC /SCANNOW Unable to Repair Four DLLs

Apesbrain · 15 Jan 2017

On my Win 7 Home Premium x86 PC, "SFC /SCANNOW" reports the following four DLLs corrupt but unable to be replaced:

FDE.DLL
FDEPLOY.DLL
GPEDIT.DLL
GPTEXT.DLL

I've also run SFC with appropriate /OFFBOOTDIR /OFFWINDIR switches from a Win 7 Home Premium x86 install DVD but I'm not sure it's the same one as originally installed this PC. This ran but arrived at the same result. I also ran CHKDSK /F /R from the DVD and it did not correct the problem. All of this was done in normal mode and in safe mode. Finally, I downloaded and ran the "System Readiness Tool" and it reported no issues.

I've attached logs that I hope will help diagnose this problem. Any assistance will be greatly appreciated.

Hi Apesbrain,
unusuall set of logs!!
What are you trying to rename?
Group policy although referenced in home premium is not used?
CBS did not finish!.

What s actually wrong??

Hi, thanks for your reply. All of this started when I noticed my Win 7 Home Premium x86 server PC was running warmer than normal. In Task Manager I saw that iexplore was running a consistent 20% of one core when it hadn't been launched at all. This happens whenever the machine is started.

I tried the usual things to get rid of it; sfc /scannow being one of them. Here is where I learned of the four irreparable DLLs. I understand from reading elsewhere that Group Policy Editor is not included in Home Premium; I must have somehow installed it but it was so long ago I don't remember. I'm not trying to rename; that folder was created by sfc. Have attached my latest CBS log.

My goal would be to replace/repair those four DLLs.

How old is your install ? It may be faster to just reinstall windows.

But, there is an absolute expert here on this stuff, he`s helped me on 3 occasions with corrupt files, Cking123

Okay I'm confused.

What is this from post 3.

All of this started when I noticed my Win 7 Home Premium x86 server PC was running warmer than normal.

What is a Home Premium "Server"?

What does temps have to do with DLL's?
If their is a overheating problem, in my opinion that should be addressed first.

From what little I do understand a "Repair Install" should fix the problem after the overheating problem is solved.

Hi ApesBrain,

Those dll entries are created on a ad hoc basis when a script is called into use, as you've surmised in this case by the SFC scannow operation, and will "dissappear" when the operation is completed.

The problem is its NOT, as can be seen in your last cbs log that DIDN'T finish either, so its stuck in a loop

Open Windows Recovery Environment.
select “Command Prompt”.
open wordpad click on File and Open
in the window that opens make a note of the Drive letter
then
type this command and hit enter.

dism.exe /image:C:\ /cleanup-image /revertpendingactions

NB
change C above to the drive letter you saw in the window.

REBOOT TO SAFE MODE
and run SFC scannow.

Thanks for the replies. Reinstalling Windows is my last choice as I've done a lot of customization on this install. I believe the overheating issue has been resolved. It is a Win 7 Home Premium PC acting in a server capacity. I am going to try the process described above by @torchwood and report back. My main objective is to solve the "corrupt DLLs" issue, if possible.

UPDATE: After following @torchwood's instructions, i still get the message from SFC that the four DLLs can not be repaired. Attached are the latest CBS logs.

Hi ApesBrain,
A clean install as you say is the last resort,
how about a repair install see this tutorial, no loss of personnal data
Repair Install

note
you will need an W7 SP1 disc, got one? if not i'll post a link.

I set this PC up years ago. At some point I decided I needed the functionality of Group Policy Editor and followed some unauthorized online instructions to install it. That is why these four files are "corrupted"; they run but are not supposed to be there. They are from an earlier version of Windows (XPSP: 5.1.2600.5512). I don't have need of them anymore, so will probably unregister and delete them. Thanks for all your help and I'm sorry for the stupid issue.

UPDATE/CLOSED: I discovered that whatever application installed GPE was kind enough to create a folder with backups of the "good" DLLs. I copied them into \SYSTEM32, rebooted, and re-ran SFC to find all is good now.
