Intel XTU 0x80070643

I wanted to get the Intel® Extreme Tuning Utility installed and play around with some overclocking on my 2017 HP Spectre X360 13″, which I’m currently running with an HP Omen e-gpu and an Nvidia GTX-1060Ti.

I downloaded the software from Intel (version 6.5.1.321) and it would not install: error 0x80070643 attempted to install on an unsupported platform.

Intel XTU unsupported platform

I found this article and used it for the basis of this post since these instructions did not work for me, although it got me 99% there.

Here’s what to do:

  • Download the installer and run it. When it gives you the error, do not close it.
  • Open the log file. You will find a path to a .msi file in there in the following folder: C:\ProgramData\Package Cache\
  • Open Explorer and find that folder. You will need local Admin rights. Copy Intel_XtuInstaller.msi to your desktop.
  • In the article linked above you run the .msi from the command line, but I only got errors, so do this instead:
  • Right-click on the MSI file and hold, drag a little ways onto a blank spot on your desktop and select “create shortcut here”.
  • Right-click > properties of the shortcut
  • In the “Start in:” field, at the end add a space and then the following DISABLEPLATFORMCHECK=1
  • It will look something like this: “C:\Users\your-user-name\Desktop\Intel_XtuInstaller.msi DISABLEPLATFORMCHECK=1
  • Click Ok
  • Double-click the shortcut

That’s it, happy overclocking and possibly damaging your machine!
