DISM Restore Source error

Having problems installing RSAT, which led me to running scf /scannow, and it reporting found corrupt files. So I'm runnning Dism /Online /Cleanup-Image /RestoreHealth which complained ...source files could not be found ... Use the "Source" option to specify the location....

Other posts cite this command to repair after you have downloaded source: Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:E:\sources\install.wim:1 /limitaccess I used the media creation tool to download the Win10 ISO. However, after I mount the ISO and take a look at the sources directory, there is NOT any "install.wim" file, nor any other path on the ISO. There is only a 302MB "boot.wim" and a 3GB "install.esd". Ran the command anyway, but it failed with same source files could not be found message. What kind of download do I need to make with MCT that has this "install.wim" file, or is there some other way to invoke DISM /RestoreHealth?

Edit
I later read the ESD is a compressed & encrypted successor to WIM. Other post had a slightly different usage. I tried Dism /Online /Cleanup-Image /RestoreHealth /Source:esd:E:\sources\install.esd:1 /limitaccess but still received Error: 0x800f081f source files could not be found

Wondering... Does repair require the ISO/WIM/ESD to be the same version as my install? Is it giving this error because it is different? MCT has no prompts for which version ISO to download. How do I download an older release if that's what I need?

Never found a way to get an older ISO via MCT. Did find another site with links to Microsoft.com for them http://windowsiso.net. The ISO checksum from that service also matched a post from Microsoft.com. With the ISO version that matched my install, DISM Restore and SFC /ScanNow were finally successful.

Alas, the problem I was hoping the DISM would fix is still unresolved. If you know how to fix 0x80073701 Referenced assembly could not be found when attempting to add Feature for the AD PowerShell module, drop me a line. I guess I may need to make a another post...
