SPAPI_E_SECTION_NOT_FOUND

SPAPI_E_SECTION_NOT_FOUND means that SetupAPI resolved the selected INF but could not find a section required by the current installation operation. A misspelled target, a missing architecture decoration, or an INF intended for another Windows target can all produce this result.

How to investigate

Compare the directive reference with the actual section header, including any architecture or target-version decoration.
Check whether the build selected the correct INF for the active platform and OS version.
Inspect SetupAPI.dev.log to see which decorated section name SetupAPI attempted to use.

Microsoft: decorated INF sections for multiple platforms
