Can I install Libre 3.5 directly over older version?

Can I install Libre 3.5 directly over older version, or do I need to first uninstall the old version?

Workaround: killing the soffice service (or whatever showed up as soffice) in the Windows Task Manager.

in general: You don’t need to uninstall older versions when installing a new version of LibreOffice - however for 3.5.0 see the release notes: http://www.libreoffice.org/download/release-notes/

For Windows users that have
LibreOffice prior to version 3.4.5
installed, either uninstall that
beforehand, or upgrade to 3.4.5.
Otherwise, the upgrade to 3.5.0 may
fail.

I would highly recommend to purge existing LibO-versions when installing via DEBS. Except you upgrade via PPA (Linux) - but the PPA is not updated right now…

i had a problem with it, it was installed 3.4.1 version, today I uninstalled 3.4.1 and after installed 3.5, without uninstall 3.4 I can’t install 3.5 it was a problems.
it for Windows OS, not *.nix

I have installed 3.5 over 3.4.4 with WPKG in a windows XP network without problems, but it´s safer to unistall first the old version.

Today I have tried to install 3.5 over 3.4.3 manually in a windows 7 64bits, and wasn´t possible. So you can try to update and the installer will update if is possible or show an error if not.
