Is anyone having problems loading the newest version of iTunes (10.6.3) using Windows Vista? My current iTunes program version 10.6.1 keeps telling me there is an update but when I try to load it the information box goes away and nothing happens. I have tried downloading the new version from Apple web site but it brings up a warning screen of " iTunes setup.exe is not commonly downloaded and could harm your computer." I select the action of run anyway and get the next error "iTunes Setup.exe is not a valid Win32 application." What Gives?
