Every PowerPack script must end by calling [Exit-PSScript](/capainstaller/powerpacks/exit-psscript/) with an explicit exit code — the `#### MAIN ####` block of the script template already does this for you (`Exit-PSScript 0` on success, or the caught exception's `HResult` on an unhandled error), so you normally don't call it yourself except to signal a controlled failure or one of the other [predefined exit codes](/capainstaller/powerpacks/exit-psscript/#predefined-exit-codes).
