however about what that information you have up there you should know that 365 works separately from any other versions.
They can't works in the same OS system in the same time together. That's why when you install 365 standalone version was replaced for good.
You can download it from MS Web site downloadoffice.getmicrosoftkey.com and use somewhere else or use it when you stop pay for subscriptions.
If you planed that, you should clean your system from 365 exactly using this uninstaller uninstall-office-from-a-pc-9dd49b83-264a-477a-8fcc-2fdf5dbf61d8 you can download.
