Hello, I have a new Intel i7 920 CPU and a new Intel DX58SO motherboard. I have tried numerous Vistaloaders but none seems to work on my system while they work fine on older computers I have here. I think it has to do something with SLIC not available or so... I know you people ask to create an Acpiscope report but that Acpiscope program doesn't seem to work on a 64bit Vista... I tried the suggestion about disabling "driver signing enforcement" by pressing F8 at start and to run it as Admin but I still receive an error "Driver failed to start". Can you do something with the image I took of my ACPI in Everest (in attachment)? I also tried the Wow5-tool but then I'm receiving an error after the last reboot: "Your program caused a divide overflow error. If the problem persists, contact your program vendor. The following file is missing or corrupt: Command.com. Type in the command of the Command Interpretor (e.g. c:\windows\command.com)". I'm not able to boot anymore when I install the Wow5-tool. Can someone please help me and explain me what I can do to finally get my Vista Ultimate activated? I'm searching and trying for several days almost fulltime now to get my Vista activated Thanks a lot in advance!
