On all of computers I have the same issue. I go to Itunes.com or apple.com and click download to download Itunes and nothing happens. I click on the download button and a screen pops up and says thank you for downloading Itunes. BUT IT IS NOT DOWNLOADED. It never downloads. I have tried on 3 separate computers, I have tried on Google Chrome, Firefox, Safari, and IE and the same thing happens. Apple doesnt seem to know how to fix it but I thought maybe someone else can help. My computers either have Windows Vista or Windows 7. The computer I really want it on is using Windows vista. I have tried every troubleshooting idea on apple's website. Any ideas?????
