Install with custom install instead of full install. Near the end of the process you can order LibreOffice to open Word, Excel etc files with LibreOffice. If you already installed it, you can change the default app to use for office files. Open Windows Explorer (not the browser). Navigate to your documents folder. Right click on a Word file, select Open with, select Browse (bottom). Navigate to LibreOffice program files folder, select swriter.exe, tick Always open files with this extension with this app, Ok to close. Note: actual texts may differ, I'm writing from memory.
