Solution 1:

Apple doesn't have a downloads page to directly download iTunes - and the link typically goes to a content delivery network.

In june, you could temporarily try downloading from https://secure-appldnld.apple.com/iTunes11/091-6059.20130605.205Rf/iTunesSetup.exe but this URL will likely change or fail in the near future. In September, the link is now https://secure-appldnld.apple.com/iTunes11/041-8597.20130918.PmmEw/iTunesSetup.exe so you can see trying to pass around direct links is not a good general solution.

The best thing to do in this case is check that you don't have any DNS blockers or other web site plug in that attempt to control / restrict downloads and try refreshing that page (or try in another browser).

Apple support might also be a good place to open a ticket, since they usually support people looking to use iTunes or Apple ID for free since you can't spend money with them without these accounts and tools.

Other things to try:

  • Change your network (have a friend download the file from a different router / internet connection) and share it over Dropbox or other means - this would fix DNS issues or other network effects.
  • Change your browser - if Chrome or Firefox have add-ons, blockers, etc. - try disabling all browser scripts and extensions or even another browser like Opera or Lynx or Safari
  • Change your computer - downloading from another computer might show the problem is with DNS settings or something else specific to your PC.

Solution 2:

I couldn't download iTunes Windows 7 64 bit from Firefox 25.0.1, but had no problem when I used IE 11. There must be some setting in Firefox that prevents the download such as if you use private browsing mode.
