I'm using LibreOffice 5.0.0.5 64 bit, and I have installed the helppack. The helppack in is the LibreOffice directory. However LibreOffice does not use the local helppack, it uses the online help.
Hi @Dirk, thanks for reporting. Are you sure, that the installed helpack is the same language than select for the UI?: Menu/Tools/LibreOffice/Language settings/Language - User interface. Must be the same language and country. E.g. if the UI is English (USA) and the helppack is for English-UK then they don't coincide, help goes to online.
You're right, that was the problem. Strange, I never had this problem before. The User Interface was English UK, and the helppack English US. I reinstalled the program and the helppack, and now everything is fine. By the way, it is a bit odd that the standard Windows version still is the 32 bit one, almost all Windows 7 and Windows 8 installations will have been 64 bit versions. Thanks for your assistance.
