Hi I have created a brand new virtual machine with Windows XP SP2 64 bit OS on it. I went to the Windows 8 upgrade site with a view to upgrading to Windows 8 Pro using the download option. First I downloaded the Windows8-UpgradeAssistant.exe. At the upgrade site it says this will check if the OS is suitable for the upgrade. However Windows8-UpgradeAssistant.exe has told me "Platform is not supported". Should I go ahead with the upgrade? Thank you. PS I have read http://kb.parallels.com/en/114985 but it does not mention Windows8-UpgradeAssistant.exe.
