I used version 1.03.04 from here but this solution should work for other versions of Epu-6 Engine and TurboV.
- After unzip run Setup.exe as administrator in compatibility mode for Windows 98 / ME (all other options will end up with failure)
- Unfortunately setup won't install all necessary components so we must do it manually. Go into "Io" folder and run AsIoIns.exe as administrator in compatibility mode for Windows 98 / ME. To be sure it installed proper driver you can also run it in compatibility mode for Windows 7
- Next go to AsSysCtrlService folder and run AsSysCtrlSrvcIns.exe and AsSysCtrlService.exe in compatibility mode for Windows 98 and then for Windows 7 as administrator.
- YOUR WINDOWS WILL RESTART AUTOMATICALLY WITHOUT PROMPT AFTER THIS STEP SO SAVE ALL YOUR WORK! From Acpi64 folder (Acpi for x32 windows version) run AsAcpiIns.exe in compatibility mode for Windows 98 and then for Windows 7 as administrator
Now after windows restart you should have working Epu-6 Engine. Overclocking, declocking and especially fans speed control works very well.
Edit: According to HRC and beck comments below doing this tip with 2-3-4-1 step sequence in some cases can give better results.
