I cannot update Apple software or remove the old one.

Question

I try to install an updated iTunes on my PC and during the download a message pops up: "The older version of Apple software cannot be removed from your computer. Call Tech Support". I tried taking off all the old versions and taking off C drive and still, no luck.

Try using Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system.

Revo will make sure that all components will be removed, even if it has to force them. When the process is over, download a new iTunes package and install it and it will work.
