Pardon, but why does the Winx64 msi setup require files in these packages to be replaced?

And who knows what else it just replaced that wasn't currently in use? Something's wrong if it wants replace unknown files for unknown reasons in all these unrelated apps.

I did select Standard Install with desktop icon and without autoload on boot.

I'll select reboot later, uninstall libreoffice, and hopefully find and delete the runonce entries before I reboot (I forgot where those are). But what else did it replace and why?

I don't think I'm being unreasonable questing this behavior and I have a bad taste in my mouth having chosen libre, kinda blindly, over the other forks.
