Installing Tableau Server on Windows requires an account with sufficient privileges to configure services, write to the file system, and manage registry settings. Let’s analyze this in depth:

Installation Requirements:

The installer creates services (e.g., Tableau Server Gateway), writes to Program Files and ProgramData, and configures TSM.

It needslocal administrative privilegeson the machine to perform these tasks.

Post-install, a "Run As" account can be set for services (e.g., NT AUTHORITY\NetworkService), but this is separate from the install account.

Option C (An account in the local administrator group): Correct.

Why: The account must be in the local Administrators group to:

Install software (UAC elevation).

Configure services and ports.

Write to protected directories (e.g., C:\Program Files\Tableau).

Examples: A local admin (e.g., Administrator) or a domain user added to the Administrators group (e.g., DOMAIN\AdminUser).

Process: Log in as this account, run the installer, and provide TSM admin credentials during setup.

Option A (A local user account): Incorrect.

A standard local user (not in Administrators) lacks permissions—installation would fail with "Access Denied" errors.

Option B (A domain user account): Incorrect unless clarified.

A domain user without local admin rights can’t install. If it’s in the Administrators group, it qualifies, but C is more specific.

Option D (NT AUTHORITY\NetworkService): Incorrect.

This is a built-in service account for running services (default "Run As" post-install), not for executing the installer—an interactive user account is required.

Why This Matters: Using the right account prevents install failures and ensures secure configuration—critical for production setups.
