WU_E_EE_INVALID_EXPRESSION
WU_E_EE_INVALID_EXPRESSION means the applicability expression was recognized as an expression, but its structure or values were invalid. Windows Update cannot make a reliable applicability decision from it.
Useful checks
- Determine whether the failure is limited to one update revision or to a whole catalog.
- Look for associated metadata, parsing, or serialization errors before the evaluator failure.
- For managed content, correct the source metadata and resynchronize rather than attempting to override applicability on clients.
