Who has able to use Vista RC1. The reason for my question back before releasing I manage to download from Microsoft site the RC1, I have not able to successfully install it. i just want to know if anyone had any problem installing it. I tried three times and it seems that is installing with no problem and when is finalizing the screens come up and out to says that the window I am trying to install it from is not compatible. Well did try frm xp64 and then I tried from scratch blanck disk drive I format the HD and all and gave me the same message. Who can help me here P.s the only reason I like to pre use it is because I wonder if my present system would be any good for it. I do Have a Athlon x64 AMd 3200 with 2gb ram of memory ATI 1600 video card and enough hadrdrive space.
