Installation Blues for VISTA - Error 80070017 (Score 1)

After great difficulty I downloaded Vista from microsoft site. This is my first mistake. Then I tried to install over my XP machine. Always it got stuck at 95% of copying files. Read the msdn forums AFTER numerous tries, got answer I am not alone. My suggestion to novice users like me to wait for stable version. It is waste of times and source of frustation. http://forums.microsoft.com/MSDN/ShowPost.aspx?Pos tID=458904&SiteID=1
