Can you provide a screenshot of the message you are getting?
Intel® Extreme Tuning Utility version 6 will provide support for Intel® Core-M processors.
I recently tried the new v18.104.22.168. During the installation it displays a message box:
"Intel Extreme Tuning Utility Setup"
"Attempted to install on an unsupported platform."
System was a Lenovo Yoga 3 Pro.
I'll look forward to v6.
