I downloaded LibreOffice_6.2.3_Win_x64.msi.
I ran this install package and it said that it completed OK, but it was not there, and it did not create a desktop shortcut as I requested. The directory in which 6.2.2.2 previously existed has vanished. Rebooting did not help. I was able to reinstall 6.2.2.2 OK which I still had in my Downloads folder. My computer runs Windows 7.
Could you please attach the screenshot of the result page where it said that it completed OK? Thanks.
