Apple's iTunes software will only install and run if additional Apple products are installed on the computer system as well. These programs include
Apple Quicktime Bonjour, Apple Software Update, Apple Mobile Device Support, and Apple Application Support.
A user installing iTunes will notice that the installer will also install
Quicktime and Bonjour and the other programs mentioned baove on the host system with no obvious option to opt out of the installation.
There is however a way to install iTunes without Bonjour, Apple Software Update, Mobile Device Support and Application Support, and avoid having all these programs run on startup when the PC boots.
Update: The last update that has been posted on the original download site dates back to 2009. We have therefore removed the download links. Instead of leaving you standing in the rain though, we have an alternative for you.
Just head over to this custom installers site and download the 32-bit or 64-bit version of iTunes from it. The installers get regularly updated so that you can be sure that you will always run the latest version of iTunes on your system.
Install a clean copy of iTunes
This can be achieved with a custom installer that can be downloaded from the Custom Installers page which offers installers for the English and multi-language versions of iTunes 188.8.131.52 and 184.108.40.206.
The only requirement other than running the installer to install iTunes is an installation of Quicktime Alternative and the Quicktime Alternative iTunes add-on which makes the program compatible with iTunes 8.
The correct sequence for installing iTunes without Quicktime and Bonjour would be therefore to install Quicktime Alternative, then the Quicktime Alternative plugin and finally iTunes using the custom installer.
The custom installer will skip the installation of aforementioned programs and services. This is great news for users who do not want to have those programs running in the background, or those who prefer to run the Quicktime Alternative program instead of the original.
The iTunes customer installer is only available for the Microsoft Windows operating system. It comes as a msi file that allows a silent installation with the switches /qb /norestart.
Please note that you can remove some of the components that are included with iTunes. Apple suggests not to remove any of those on the official support site though, as it may impact functionality.
Don't uninstall these components in a different order, or only uninstall some of them. Doing so might have unintended effects. After you uninstall a component, you might be prompted to restart your computer. Wait to restart your computer until you're finished removing all of the components.
