I am trying to install Windows 8 (via Parallels) using this version: http://www.amazon.com/Windows-System...ords=Windows+8 It seemed like it should be for new installs, but when I get to the point of entering my key I am told the key is not valid. I can only assume this is because it's the same old crap where you need to be upgrading from a pervious version of Windows. Do I need to start with Win7 then go to Win8. I hate Windows, but Excel is still much better. This is why I stopped using Windows in the first place (along with the crappy machines it comes installed on).
