What does Windows error code 4575 (ERROR_PLATFORM_MANIFEST_NOT_ACTIVE) mean?

ERROR_PLATFORM_MANIFEST_NOT_ACTIVE

No active Platform Manifest exists on this system.

ERROR_PLATFORM_MANIFEST_NOT_ACTIVE is Win32 error 4575 (0x11DF) and belongs to Platform Manifest authorization.

Likely causes

• the system has no active Platform Manifest against which authorization can be evaluated.
• the active platform identity disagrees with provisioning state, installed manifests, activation events, and boot trust state.
• the provisioning pipeline did not restore or activate the platform-approved manifest before installing components that depend on it.

Troubleshooting steps

• Record provisioning state, installed manifests, activation events, and boot trust state.
• Record device identity and the active Platform Manifest generation.

What to verify

Verify whether the system has no active Platform Manifest against which authorization can be evaluated. Check provisioning state, installed manifests, activation events, and boot trust state, the device identity, and the active Platform Manifest generation.

Handling, retry, and recovery

Restore or activate the platform-approved manifest before installing components that depend on it. Preserve the artifact and authorization evidence before changing provisioning state.

Practical example

A recovered device has manifest files on disk but none activated, and platform-specific servicing is blocked.
