error when install LO 4.3.4.1

When i try to update from LO 4.3.0.4 to the new version 4.3.4.1 French version
i’m getting a ****error code 1913…
impossible to update file ini…

i’m using windows 7 home premium 64-bit SP 1
basic language is french

i’m also the administrator of the computer

i’ve checked in C:\Program files (x86)LibreOffice 4\program\setup.ini. and the file exists
but that’s all that i understand of it …i’m NOT a skilled programmer, only a user

What is going wrong

regards,

ludo

Nobody needs to be a programmer to install LibO. However, to provide an answer more information is needed. Please have a look at What information should I include in a question in addition to OS and LibreOffice version? - #4 by ROSt53
