LO 5.3.2.2: msi silent install: UI_LANGS property seems not to work as expected

Hi,

i tried to do a silent msi install, selecting only a few ui languages:

> https://wiki.documentfoundation.org/Deployment_and_Migration
> With LibreOffice 3.5.5 and higher, language selection works as follows.
> msiexec /i Lib...._.msi UI_LANGS=en_US,de

msiexec /qb /passive /i LibreOffice_5.3.2_Win_x86.msi /L*V lo_install.log 
INSTALLLOCATION="C:\Program Files (x86)\LibreOffice" ALLUSERS=1 ADDLOCAL=ALL CREATEDESKTOPLINK=0 
REGISTER_NO_MSO_TYPES=1 UI_LANGS=en_US,de ISCHECKFORPRODUCTUPDATES=0 REBOOTYESNO=No QUICKSTART=1 
VC_REDIST=1 
REMOVE=gm_o_Onlineupdate,gm_r_ex_Dictionary_Af,gm_r_ex_Dictionary_An,gm_r_ex_Dictionary_Ar,...

but it seems, UI_LANGS property is ignored - all ui languages ire installed.

any hints?

Oliver
