All our installers will allow you to freely choose their installation folder, which can be any place, even on a different drive, that doesn't (and it's best if it's not) the main sim folder.
If you already installed them in their default folder and you now realized it wasn't a good choice, uninstall *everything* AND Reply YES to the question "Do you want to remove the Addon Manager ?".
This will CLEAR your previous choice, allowing to either accept the default location (which it's FINE if you have enough space on C:), or change it to another drive/folder.
