Solved DISM Error: 0xc1420117 when trying to unmount and commit.

[Paul Black]

Good evening,

I have successfully integrated updates into the install.wim.

I then used the command:
Dism /Unmount-WIM /MountDir:C:\Win7ISO\OFFLine /Commit

It says: Error: 0xc1420117

The directory could not be completely unmounted.
This is usually due to applications that still have files opened withing the directory.
Close these files and unmount again to complete the unmount image.
Do I need to delete the directory C:\Win7ISO\OFFLine and try again?

Any ideas please?

Thanks in advance.

EDIT:
Does it make a difference the fact that I put the offline image in the folder where the extracted ISO files are?
Do I need to delete that folder first and try again?

Good afternoon,

I have tried this again and still have an error.
I have attached a screenshot of the CMD Prompt and the DISM.log (cut down to include the error part I think!).

I created the directory:

mkdir C:\Win7ISO\OFFLine

The mount command is:

Dism /Mount-WIM /WimFile:C:\Win7ISO\sources\install.wim /Name:"Windows 7 HOMEPREMIUM" /MountDir:C:\Win7ISO\OFFLine

I can't move on until I get this sorted! :banghead:

Thanks in advance.

Update:

I ran: DISM /Get-MountedWimInfo and got the following results and I also checked the mounted OFFLine directory which shows it as being empty.

OK, I have done some testing.

I created a directory to mount the install.wim to: C:\Win7ISO\OFFLine

I mounted the install.wim: Dism /Mount-WIM /WimFile:C:\Win7ISO\sources\install.wim /Name:"Windows 7 HOMEPREMIUM" /MountDir:C:\Win7ISO\OFFLine

I unmounted and committed: Dism /Unmount-WIM /MountDir:C:\Win7ISO\OFFLine /Commit

I still got the error which proves it must be something above.

It saves the image OK but will not unmount it properly.

Any help will be greatly appreciated.
