1) Went here: https://downloadcenter.intel.com/
2) Downloaded update tool. Update tells me I have version 10.0.10586 installed, and the latest version is 10.1.1.14. Device Manager confirms driver version. "Infinst" folder doesn't exist in registry, so can't confirm version that way.
3) I download latest version and install fails from and "Unknown Error"
It gives me to option to "View Log Files", but there are 3 of them and they are super long:
"Chipset_20160522160728.log"
"Chipset_20160522160728_0_SetupChipsetx64.msi.log"
"Chipset_20160522160728_0_SetupChipsetx64.msi_rollback.log"
If anyone needs one these these logs to help, I can post as requested.
