No luck on XP, it doesn't install. This is a fresh install without any updates, so maybe something is still missing?

I installed HECI, the required .NET 3.5 SP1, and the latest Chipset driver, so not sure what else is missing but it doesn't ask for anything else during the install?



Error 1722.There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor. Action RegisterChipsetAccess.38BEA05C_BD35_41D3_A167_42B8 8B949E03, location: C:\Program Files\Common Files\Intel\Intel Extreme Tuning Utility\, command: regsvr32.exe /s "C:\Program Files\Common Files\Intel\Intel Extreme Tuning Utility\ChipsetAccess.dll"
Looks like missing .dll maybe?

Ahh, found the problem in the readme linked above
