SPAPI_E_NO_ASSOCIATED_CLASS

SPAPI_E_NO_ASSOCIATED_CLASS means that an operation requiring a device setup class was requested for an INF, device information set, or device element that has no associated class. Class information determines how Windows groups installation behavior and which class installer rules may apply.

What to check

For an INF, verify the Class and ClassGuid entries in its Version section when a device setup class is required.
For SetupDi code, create or open the device information set with the intended class context before calling class-dependent functions.
Confirm that the class is a valid device setup class, not merely a device interface class.
