SPAPI_E_SIGNATURE_OSATTRIBUTE_MISMATCH
SPAPI_E_SIGNATURE_OSATTRIBUTE_MISMATCH (0x800F0244) is a Windows SetupAPI driver-installation error. This code means the package's signature metadata indicates testing or compliance attributes for a different Windows version. It is a compatibility warning/error path that should be resolved by choosing a package intended for the installed Windows release.
What to check
- Check the package release notes and INF decorations for the current Windows version and architecture.
- Compare the device hardware IDs against the vendor's supported package list.
- Do not assume an older signed package is safe merely because the catalog itself verifies.
