I have attempted to run the Windows Vista Upgrade Advisor beta software on\nboth my home laptop and my desktop computer at work. In both instances, the\nHardware Assessment section has displayed an error message: "Windows Vista\nUpgrade Advisor could not run Winsat. System compatibility status could not\nbe evaluated. " I cannot find a program called WinSat on my system, nor a\ndownloadable installer for it online. Can someone explain to me why this has\nhappened?
