ERROR_WMI_INVALID_MOF

MOF is a schema contract, not just a text file

Managed Object Format defines CIM classes, qualifiers, properties, and relationships that a WMI provider exposes. This status points to invalid MOF information: the source can have a grammar error, a type or qualifier inconsistency, an invalid relationship to an existing schema, or a binary MOF resource that fails WMI validation.

For WDM providers, the driver workflow is distinct from merely compiling a user-mode MOF into a repository. The driver MOF is compiled into a binary resource and should be validated for WMI data and event blocks. A successful C or C++ build does not prove that the published management schema is valid.

Validation before deployment

Run the MOF compiler in validation mode and retain its exact diagnostic output with the source revision.
For a driver binary MOF, use the WMI-aware compilation path or the documented binary checker before embedding the resource.
Verify namespace, class inheritance, qualifiers, and property types against the installed schema rather than silently overwriting conflicts.
