This article concerns version 4.1.5 :

LibreOffice is an open source completely free alternative to Microsoft Office. There are some deployment tips but they are not well documented.

Habitual MSI silent switches applies with LibreOffice and there is also some properties you can add to configure the software properly.

Here is a list of the silent switches and properties that I use for my silent deploy :

/passive (Silent mode but passive so you can see the progressbar)
/norestart (Suppress reboot needs after the installation)
ALLUSERS=1 (Installs for all users on the computer)
CREATEDESKTOPLINK=0 (Do not create shortcuts on the desktop)
REGISTER_ALL_MSO_TYPES=0 (Do not register Microsoft Office extensions with LibreOffice)
REGISTER_NO_MSO_TYPES=1 (Do not register Microsoft Office extensions with LibreOffice)
ISCHECKFORPRODUCTUPDATES=0 (Disable auto-updates)
QUICKSTART=1 (Enable the software Quickstart)
ADDLOCAL=ALL (Installs all components on the local computer)
UI_LANGS=en_US,fr,es (Interface languages. Here it installs US english, french and spanish for the user interface)
REMOVE= (Removes modules. I used it for removing dictionaries that I didn't wanted like the next command)
Exemple : REMOVE=gm_r_ex_Dictionary_Af,gm_r_ex_Dictionary_An,gm_r_ex_Dictionary_Ar,gm_r_ex_Dictionary_Be,gm_r_ex_Dictionary_Bg,gm_r_ex_Dictionary_Bn,gm_r_ex_Dictionary_Br,gm_r_ex_Dictionary_Bs,gm_r_ex_Dictionary_Ca,gm_r_ex_Dictionary_Cs,gm_r_ex_Dictionary_Da,gm_r_ex_Dictionary_De,gm_r_ex_Dictionary_El,gm_r_ex_Dictionary_Et,gm_r_ex_Dictionary_Gd,gm_r_ex_Dictionary_Gl,gm_r_ex_Dictionary_Gu,gm_r_ex_Dictionary_He,gm_r_ex_Dictionary_Hi,gm_r_ex_Dictionary_Hr,gm_r_ex_Dictionary_Hu,gm_r_ex_Dictionary_It,gm_r_ex_Dictionary_Lt,gm_r_ex_Dictionary_Lv,gm_r_ex_Dictionary_Ne,gm_r_ex_Dictionary_Nl,gm_r_ex_Dictionary_No,gm_r_ex_Dictionary_Oc,gm_r_ex_Dictionary_Pl,gm_r_ex_Dictionary_Pt_Br,gm_r_ex_Dictionary_Pt_Pt,gm_r_ex_Dictionary_Ro,gm_r_ex_Dictionary_Ru,gm_r_ex_Dictionary_Si,gm_r_ex_Dictionary_Sk,gm_r_ex_Dictionary_Sl,gm_r_ex_Dictionary_Sr,gm_r_ex_Dictionary_Sv,gm_r_ex_Dictionary_Te,gm_r_ex_Dictionary_Th,gm_r_ex_Dictionary_Uk,gm_r_ex_Dictionary_Vi,gm_r_ex_Dictionary_Zu

Also, if you want other configurations like default extensions, autosave features and everything in the options, you need to copy %AppData%\LibreOffice\4\user configured folder into every existing profiles in the computer. I created a VBS function to do this.

Note that Quickstart is buggy so I needed to place a shortcut by script in the start section of the Start Menu.

A sample of the installation command would be :

Msiexec /qb! /i LibreOffice_4.1.5_Win_x86.msi /passive /norestart ALLUSERS=1 CREATEDESKTOPLINK=0 REGISTER_ALL_MSO_TYPES=0 REGISTER_NO_MSO_TYPES=1 ISCHECKFORPRODUCTUPDATES=0 QUICKSTART=1 ADDLOCAL=ALL UI_LANGS=en_US,fr,es REMOVE=gm_r_ex_Dictionary_Af,gm_r_ex_Dictionary_An,gm_r_ex_Dictionary_Ar,gm_r_ex_Dictionary_Be,gm_r_ex_Dictionary_Bg,gm_r_ex_Dictionary_Bn,gm_r_ex_Dictionary_Br,gm_r_ex_Dictionary_Bs,gm_r_ex_Dictionary_Ca,gm_r_ex_Dictionary_Cs,gm_r_ex_Dictionary_Da,gm_r_ex_Dictionary_De,gm_r_ex_Dictionary_El,gm_r_ex_Dictionary_Et,gm_r_ex_Dictionary_Gd,gm_r_ex_Dictionary_Gl,gm_r_ex_Dictionary_Gu,gm_r_ex_Dictionary_He,gm_r_ex_Dictionary_Hi,gm_r_ex_Dictionary_Hr,gm_r_ex_Dictionary_Hu,gm_r_ex_Dictionary_It,gm_r_ex_Dictionary_Lt,gm_r_ex_Dictionary_Lv,gm_r_ex_Dictionary_Ne,gm_r_ex_Dictionary_Nl,gm_r_ex_Dictionary_No,gm_r_ex_Dictionary_Oc,gm_r_ex_Dictionary_Pl,gm_r_ex_Dictionary_Pt_Br,gm_r_ex_Dictionary_Pt_Pt,gm_r_ex_Dictionary_Ro,gm_r_ex_Dictionary_Ru,gm_r_ex_Dictionary_Si,gm_r_ex_Dictionary_Sk,gm_r_ex_Dictionary_Sl,gm_r_ex_Dictionary_Sr,gm_r_ex_Dictionary_Sv,gm_r_ex_Dictionary_Te,gm_r_ex_Dictionary_Th,gm_r_ex_Dictionary_Uk,gm_r_ex_Dictionary_Vi,gm_r_ex_Dictionary_Zu
