If your EPM is hosted on a SharePoint farm, navigate to: [YourSiteCollection]/_layouts/15/EPM/EPMAddinDownload.aspx This page automatically detects your Office architecture and offers the correct 64-bit download.

In the or Home pane, look for the Install EPM Add-in for Microsoft Office link.

Need the direct download link? Access your Volume Licensing Service Center or Microsoft 365 Admin Center. If you are a home user, note that the EPM add-in requires a valid Project Server or Project Online license – it does not function with standalone Office Home & Business.

As of 2025, Microsoft has not released a new standalone "EPM Add-in for Office 64-bit" for Project Server Subscription Edition (SE) or Project Operations. The future is API-driven.
