Web Host Automation (HELM Authors) sold the control panel rights and code some years ago to Parallels.
Since then development and support has ceased, so HELM is not considered an End-of-Life (EOL) dead product and no longer available for new installations.
Astutium have extensive experience in migrating HELM setups onto more modern, supportable platforms like WebSitePanel - contact our Hosting Sales Team to discuss your exact requirements.
