Hi,
I want to upgrade the my existing LibreOffice to latest version with the below few conditions.
Regards,
Sumanth
And your OS is… ?
windows os
Your #1 is typically the default: LibreOffice installer knows how to deal with the older version, and takes advantage out of the existing installation by analysing the installed component set, and automatically selecting what has been installed earlier, instead of suggesting the default installation set (which is useful if you have a non-default set installed). So you see, that it’s absolutely not required to uninstall LibreOffice first. (But note that this could not work when your older installation MSI database is somehow damaged, which could require a repair, which is beyond LibreOffice responsibility and is a system service failure.) However, the “With out uninstalling the existing version of LibreOffice” allows very different interpretations, three more that I could imagine are “I want to keep my user settings, so that I don’t need to set up toolbars etc after upgrade” (this is the default, since LibreOffice settings are kept in the user profile independent of the installation files), “I want the newer LibreOffice to co-exist with the older one” (somewhat conflicting with your following requirement; if this is wanted, portable version also could be considered), and “I want that the installation process be as quick as possible, so the installation process itself must not uninstall the older one, but only modify what is modified” (this one matching your following requirement better).
The #2 is impossible at the moment. There is tdf#68274, but it’s far from completion, and is not actively worked on lately as far as I can tell. So - no, the only actual option is downloading the entire official MSI installer (~300 MB); and note that, while not requiring you to uninstall your older version manually first, it would still uninstall it itself when installing.
The #3 may be done using
msiexec /i d:\path\to\libreoffice.msi /qn
You may consult the msiexec documentation and LibreOffice deployment wiki section.
Thank you so much for your wonderful explanation.
