When I try to install RC, I get the message
This computer is not compliant with the Advanced Configuration and Power Interface (ACPI) standard. Windows must be installed onto a computer that supports ACPI.

However this is a relatively new computer whcih is ACPI compliant, at least according to the BIOS screens. What am I missing? When I run the Win 7 compatibility test it says that my machine is ok.
i had the same problem, i took out all but one stick of ram and i was able to install.
