I have a recently bought iPhone 4. I'm running itunes 9.something on a toshiba laptop windows 7 64-bit. I want to connect my new iphone to itunes so I can sync it and update to iOS 5, but when I connect is says I need the new itunes, 10.5. When I go to update, it downloads, but when installing I get the following message "itunes installer intended for 32bit version of windows download 64bit installer instead" On apples website I tried to download itunes manually from there (the 64 bit version) and get the same result. There is a little side note towards the bottom left of the page that says "■64-bit editions of Windows Vista or Windows 7 require the iTunes 64-bit installer" and the "64-bit installer" text is a link, but only takes you to the download itunes 10.5 page, which leads back to the same problem. Has anyone else encountered this problem? I've gone through all the apple support documents to no avail, and scoured the web and can't find any help. I can't find any way to download itunes 10.5 or the "64-bit installer" and have tried for hours. Can anyone please help?
