SPAPI_E_NO_CLASSINSTALL_PARAMS

SPAPI_E_NO_CLASSINSTALL_PARAMS means that an operation expects class-install parameters, but none have been attached to the device information set or selected device element. The parameter block is operation-specific, so a structure for one DIF request cannot be assumed valid for another.

What to check

Identify the DIF operation being processed and use its documented class-install parameter structure.
Set the parameters on the same device information set or device element that the later operation uses.
Check structure size, install-function code, and lifetime before calling the corresponding SetupDi function.
