STATUS_CLIP_LICENSE_NOT_SIGNED
The license has no acceptable authenticity proof
CLiP relies on signed license objects so Windows can verify both integrity and issuing authority. This status means the object presented as a license has no signature in the form required by the platform. It is distinct from an invalid signature and from an unknown signer because validation cannot begin without the expected signature data.
Common explanations are a truncated artifact, a development placeholder reaching a production path, an incorrectly exported enterprise license, or corruption in a deployment package. The platform should not be configured to accept unsigned licensing material.
What to inspect
- Verify the license file or record length and acquisition source.
- Compare the deployment bundle with the original signed package and license artifacts.
- Review Store, AppX deployment, and ClipSVC events for an interrupted provisioning transaction.
- Reacquire the signed license rather than attempting to sign the object locally.
