Here are some articles I have written on how to resolve some errors relating to Windows Images. Error 0xc1570103: The license file was not found in the specified path, and how to fix error 0xc1510114-The wim file needs to be remounted.

The below image is the output I got while trying to add packages to an install.wim file.

Fix the system cannot find the file
Note: The path and Cabinet (Cab) files were correctly specified, but this error was still prompted because the PackageFamilyName (UWP) was renamed, and the DISM tool could not install the cabinet file with the file name. This sounds a bit strange as some other packages were installed this way.
Solution: I was able to resolve this issue, by mounting the Feature on Demand (FoD) ISO and re-copied the needed packages without renaming them. Here is an example of a package “Microsoft-Windows-TabletPCMath-Package~31bf3856ad364e35~amd64~~.cab”. In this way, the packages were installed successfully. Please see this article on how to how to Add Packages to Windows image the DISM Tool.
dism /Image:G:\Path-to-the-mounted-wim-file\<MountedZ(mountedDirectory)> /Add-Package /PackagePath:G:\path-to-the-package\the-cabinet(cab)-file-to-be-added
After successfully adding the package to the WIM file, you should get a message as shown belowDeployment Image Servicing and Management tool
