SPAPI_E_WRONG_INF_STYLE

SPAPI_E_WRONG_INF_STYLE means that the caller asked SetupAPI to process an INF in one style, but the selected file was recognized as a different style. This commonly occurs when code assumes a device-driver INF while receiving another setup-information format or an unexpected generated file.

What to check

Log the fully qualified INF path that reached SetupAPI and verify it is the intended package file.
Confirm that the API flags and installation flow are appropriate for a device-driver INF.
Check build and packaging scripts for filename collisions or stale copied INF files.
