Have you tried running this after setting a password for the root user?

lxrun.exe /setdefaultuser root
bash.exe -c "passwd root"

I did have a password set for the root user when I ran it. I ran your commands (just to be sure) and tried it again, same result. I also tried reinstalling (lxrun /uninstall /full, lxrun /install) with the same results unfortunately.

@brianbob Are you running bash.exe as an admin user? Could you try running the installation out of a directory that is not /mnt/c/Windows/System32? It looks the install might be trying to create files in the current working directory which in your above example appears to be \windows\system32.
