ERROR_PACKAGES_REPUTATION_CHECK_FAILED
Application reputation validation did not approve deployment
ERROR_PACKAGES_REPUTATION_CHECK_FAILED is associated with deployment paths that request Microsoft Defender SmartScreen evaluation and user verification before package installation. Reputation is separate from package signature validity: a correctly signed package can still lack sufficient reputation or be blocked by organizational SmartScreen policy.
Verify the package signature and publisher first, then inspect SmartScreen and deployment events and the effective device policy. For external distribution, maintain stable publisher signing and submit clean, consistently signed packages; do not rotate identities unnecessarily. In an enterprise, determine whether users may bypass warnings or whether policy mandates blocking.
What to inspect
- Separate signature trust from SmartScreen reputation.
- Check effective SmartScreen and App Install Control policy.
- Preserve a stable verified publisher identity across releases.
