My guess would be that you're receiving this error because the machine
you're trying to open the registry on is not currently available or is
not accessible for some other reason (security, firewall, etc). You can
tell the script to continue by either trapping the error or just
setting the global $ErrorActionPreference variable to
"SilentlyContinue" before running the script. This way, when the script
encounters a machine that it cannot reach it will just move onto the
next machine.
