Thank you for contacting Intel Communities.
The Intel® XTU is a tool that works on unlocked Intel® Core™ processors only.
Please bear in mind that the Intel® Core™ i7-6700HQ Processor is not an unlocked processor, therefore; you may face issues like the one you are reporting as the tool is not meant to be used with that processor.
