SPAPI_E_AUTHENTICODE_TRUST_NOT_ESTABLISHED
SPAPI_E_AUTHENTICODE_TRUST_NOT_ESTABLISHED (0x800F0242) is a Windows SetupAPI driver-installation error. This error means the catalog has a signature, but Windows could not establish that its publisher is trusted in the current system context. It is different from a missing catalog or a missing file hash.
What to check
- Check the certificate chain, validity period, and revocation reachability for the catalog signer.
- Make sure the package was not modified after signing.
- Use an updated package from the vendor rather than bypassing signature checks.
