Unable to install iTunes: problem with the Windows Installer Package

This error happened maybe because you downloaded a different version of the installer not designed for your operating system because iTunes for Windows is available in different versions: for x86 or 32-bit and for x64 or 64-bit. In this case, though sometimes you can install an x86 application on x64 operating system but since the program provides a separate version, it is just right to use the appropriate version designed for your operating system.

If you have an x86 Microsoft Windows, you can download iTunes from the default download page, iTunes 11.1.5 for Windows. It supports Windows XP Service Pack 2 and up, Windows Vista, Windows 7, and Windows 8 all x86. But if you have an x64 Microsoft Windows, you need to download the iTunes 11.1.5 for Windows x64. It requires Windows Vista, Windows 7, and Windows 8 all x64.

The x64 version of iTunes doesn’t support x64 Microsoft Windows XP. Since it doesn’t need any other special component, the latest version should work. If running the installer throws back a message, try starting it as administrator. Right-click on the iTunes installer and select Properties. Select Compatibility tab, under Privilege Level section, check “Run this program as an administrator” and click OK. Start the installer again and see if it works.
