I upgraded to Libreoffice 5.1 but the new help files will not load - the installer looks for v. 4.24 help package. what can I do?

i searched for the file LibreOffice_4.2_4_Win_x86_helppack_en-US but it does not exist on my system

Try download from http://www.libreoffice.org/download/libreoffice-fresh/?type=win-x86&version=5.1&lang=pick
