I am facing a problem with downloading the iTunes 10.5 version. It says that there is a problem with the Windows Installer Package. And then after that I went to the Updates and updated the Windows. Even after that I'm facing a diffuculty in installing the iTunes. Please get back asap, as I want to update my iPod with that, because the iOS5(the iPod update) can be installed only if iTunes 10.5 is downloaded. My PC has Windows Vista 32-bit.
