SPAPI_E_INVALID_CLASS_INSTALLER

SPAPI_E_INVALID_CLASS_INSTALLER means that SetupAPI found an invalid class-installer registration for the selected device setup class. The failure is about the installer configuration rather than the device driver binary alone; class installer loading cannot proceed with inconsistent or malformed registration data.

What to check

Inspect the class registration used by the device and verify the configured installer path and entry points.
Check recent driver package changes that modify ClassInstall32 or co-installer-related settings.
Use SetupAPI.dev.log to separate class-installer loading errors from ordinary INF parsing or driver-ranking failures.
