Fix error: Install and uninstall windows LibreOffice.

When you try to install or uninstall LibreOffice software then this will want the old instalation file.
For example I want to install the new LibreOffice 5.1.52 software and the instalation file try to find the old LibreOffice_5.1.4_Win_x64.msi.
I fix this with download the LibreOfice_5.1.4.2_Win_x64.msi from here and renamed with LibreOffice_5.1.4_Win_x64.msi.
Also you need to use task manager to close all firefox browser tasks.
This will allow to install the new version of LibreOffice software.
