I installed LibreOffice on Windows XP without any service packs intalled. LibreOffice failed to launch and gave the error message "The procedure entry point EncodePointer could not be located in the dynamic link library KERNEL32.dll". I tried to start Writer directly with the same result. Google suggests this message means LibreOffice requires SP2. The system requirements page (http://www.libreoffice.org/get-help/system-requirements/) doesn't mention this.
Thanks Robin for the issue. And sorry for the trouble it gave you.
