Intel RST fails to install on Windows 10 Version 1809


Installation around 80% progress and then it fails with "Fatal error during installation" message.



Excerpt from %USERPROFILE%\Intel\Logs\IntelRST_MSI.log around where I think the error appears.

Previous version installed just fine previously. In fact it is the one mentioned in the log above, I will try to manually uninstall it first and then install the new one, maybe that will help.

Uninstalling previous Intel RST version (, rebooting and then installing the new version solved the issue for me, thank you.


Additional note:

Having to apply the same on another system with similar results, I realize something that the two have in common is the TEMP variable pointing to an OSFMount RAMDrive.


Trying to uninstall the older version on this system failed with something like "unable to extract language" or "unable to load language". Opening up an Administrtor CMD, setting temporarily in the console the user TEMP and TMP variable pointing to the system drive, works to uninstall it.


I haven't retried the whole scenario from the start, possibly changing the TEMP variable to a system drive in the first place and update in place, maybe that would have worked from the beginning. The RAMDrive performs fine otherwise, no idea why it would influnce the installation process.
