Just a heads-up here. I just downloaded LibreOffice v6.4.5 for Windows 10 64bit to review for a user who thinks they have to pay $$$ for Microsoft Office for their office productivity needs. I did a “Save As” to my desired temp work folder. It saved it as a “.man” extension file. A little research showed this is a known issue when using Internet Explorer to do the download. Of course Windows has no idea what a “.man” file is. The easy fix is just to rename the “.man” extension to “.msi”. The install will then run as expected. HTH
