Find the original source of DISM.exe and install Windows updates.
Hey, I'm an MCSE specialist, but that just means you should consult another expert. You need to run dsim toward a mounted ISO image to refresh it, or the USB drive you have booted in. For older images—like those from System Center Configuration Manager or other auto-install tools—make sure you verify the file is correct and accessible. If you proceed without source, check your current Windows installation's WIM file.
I’ve consistently managed to run it during installation, just ensure you’re using an admin command prompt, not a regular user one. There have been instances where the sfc /scannow flagged issues it couldn’t resolve, but after applying the suggested steps they were fixed.
