Both Dism and Health Image fail, reporting missing source files

I'm trying to repair a W10 installation, and so I ran Dism. Unfortunately it fails, and reports that it can't locate the source files -

Error - cannot locate the source files:


The example I used for running Dism:


File Explorer, showing drive G, which was used when I ran Dism:



I then used Image Health tool instead. Unfortunately, this fails too, with the same issue -



I'm not sure if this is important, but the instructions for the Image Health tool says -

Step 2: Right-Click IMAGE_HEALTH.CMD > Select Properties > Select Unblock

When I right clicked on this .cmd file, I couldn't see an option/property that said "Unblock" -

Thanks a lot for any advice on this issue!

I would say your issue is that you are trying to do this to a DVD. Copy the file to a USB thumb drive so that changes can be made.

When using Dism, I download the Win10_1607_EnglishInternational_x64.iso file from MS Techbench, right clicked on this file, then selected the Mount option. It mounted the iso file OK, and created a virtual G: drive letter DVD drive. This was done so that Dism could then use the install.wim file found inside the G:\sources folder. Unfortunately, Dism reported that it was unable to locate it.

Are you United States or United Kingdom version of Windows 10? English International is for United Kingdom.

In the command prompt (admin) window run:

dism /online /get-intl

That will display the default language installed. If it says US, then you need just the standard Windows 10 ISO file, not the international file.

Code:

C:\Windows\system32>dism /online /get-intl

Reporting online international settings.

Thanks for the tip. I'm in the UK, and dism get-intl returns OK:

Are you sure you have 64 bit Windows installed?

I have the 64-bit version installed:

Mounting an ISO runs in a virtual space, not sure you can run DISM that way.

Normally you can. And I just did on my computer to be sure.

@W10User123, the only other thing I can suggest is to try :2 after index.wim in the command instead of :1. Don't know if it will work or not, but in the standard Windows 10 ISO file index 1 (:1) is Windows 10 Pro and index 2 (:2) is Windows 10 Home. That being said, I just ran the dism restorehealth command on my Windows 10 Home laptop using index 1 with a mounted standard Windows 10 ISO file and it completed successfully anyway.

Thanks Navy, that's nice to know.

OP, are you running DISM from as admin?
