itunes is not downloading on my pc

That's unfortunate.

Try a different browser.

Try posting or searching for the exact error that is being displayed, if one exists.

Make sure that its just not iTunes you have deleted adn trying to install because most likely that's always gonna happen.

follow this one:

its because the download link has no file... (" shanny101: http://appldnld.apple.com " which that link is what is used to download the file)
