Dism - The directory could not be completely unmounted - process explorer can't find open processes and unmounting fails

Question

Hi all,
Installed WAIK on server 2008 R2 64 bit. I'm setting up some boot images, and am having a real hard time getting drivers to integrate into the driver store in the boot images.
What I'm finding is that when adding drivers to the boot image the gui hangs part way through over 50% of the time using Dell 760 or HP NX9420 drivers extracted to pull out the inf files. It's really flakey and will work after a couple of attempts and when the wind is right.
The main problem is that when the process fails the image is left open, so using dism to list mounted images and then umount the open images is the only way to try again.
However, some images won't unmount and the unmount process displays the following:
C:\Windows\system32>dism /get-mountedwiminfo

Unmounting image

Error: 0xc1420117
The directory could not be completely unmounted.  This is usually due to applica
tions that still have files opened within the mount directory.  Close these file
s and unmount again to complete the unmount process.
The DISM log file can be found at C:\Windows\Logs\DISM\dism.log
Using process explorer shows no running processes that have the files open and the dism.log file shows:

Rebooting the server clears the lock, but it's really becoming a joke, as I can create a boot image with the drivers, but then going back into add another driver causes the gui to not respond.
Any suggestions gratefully accepted. - Matt.

Hi all,
had same problem unmounting the wim file using Windows 7 Pro 32bit.
My solution was: Checking for "wrong" Dism.exe
Preparing a WinPE I followed the steps in the help of AIK. I ran the
copype.cmd batch. When it was finished, it said that it added something
to the path environment variable. It was clear that it did so in order
to find the tools needed for the further steps. As long as everything
worked, I didn't give it a second thought. Then I could not unmount the
WIM.
I looked at the PATH variable: NO entry pointed to the directory where
dism.exe was in. (In my case that would have been
     c:\program files\windows aik\tools\x86\servicing
Magically, dism.exe started from everywhere though.
Doing a      dir c:\dism.exe /s /a     showed I had a Dism.exe in
c:\windows\system32, as well. This one has a file size different from
the correct one. Obviously I had started this one (because PATH points
there).
Starting the correct dism.exe let me unmount the WIM without problems.

Robert
