Running XP-Pro sp2 here. Wouldn't let me run the 'advisor' until I installed .Net Vers.1 (la-de-da ) Then it ran,but had to tell ZA to let it access the internet for a "COM surrogate" whatever. Now that I've toodled over here,checked ZA and it now has "another" entry with all question marks for "Vista Upgrade Advisor". ???? Think it's gon'na want to call home? Hmmm?? Yep,,I think so. So it's going to be locked right now! Don't care what the install "agreement" said!!
Stuff it M$!!

Oh yeah,one more lil' thing. I realize this is a 'beta' staged program,but it said I would need a TV tuner card to be able to use the video functions. Well,guess what? I have the ATI AIWonder Radeon 9600 card already installed and pull video from everywhere already! Surprised it didn't say I'd also need two tin cans and a very long piece of string to get VOIP too...
