I Can't Install iTunes
If you own an Apple iPod or iPhone, you're going to need to install iTunes onto your computer. iTunes is a program designed by Apple and the only official way to transfer content from your computer to these devices. If you're having a problem installing iTunes onto your computer, it is due to one of two things: Either you have an installation file that isn't compatible with your operating system, or you aren't logged in as your computer's system administrator.
Click "Start" and choose "Log Off." Log back into your computer as the administrator account. Typically the administrator account on computers is the only account that has the authority to download and install new software, even when that software is something as harmless as Apple's iTunes.
Click "Start," right-click "Computer" and choose "Properties." Make a note of exactly what type of operating system you're running and whether that operating system is 32-bit or 64-bit. You need this information to verify that you're downloading the correct version of iTunes from Apple's website.
Open your Web browser and go to Apple's iTunes download site (see "Resources").
Click the circle next to the version of iTunes that is compatible with your operating system. Click "Download Now" to download the appropriate installation file.
Double-click on the iTunes EXE installation file. iTunes should now install onto your computer with no problems.
