To successfully install the Health Cloud managed package, administrators must enable several foundational features. Person Accounts are required for the patient data model, and the standard procedure is to request enablement via a Salesforce support case. The "Contacts to Multiple Accounts" feature is necessary to model complex patient relationships with various providers and facilities. Finally, Chatter must be enabled to support the collaborative care team features inherent in Health Cloud. These prerequisites ensure the core components that Health Cloud depends on are active in the org before installation.

D: Making data protection details available is a data privacy configuration step, not a technical prerequisite for package installation.

E: The official Health Cloud installation guide specifies logging a support case to enable Person Accounts, making self-enablement from Setup an incorrect step.
