hi,

i try using zotero /libreoffice integration installation but only an "installation failed" appeared.
it says that i must do it manualy.
well, it seems to be "present" in libreoffice writer, since there are some buttons " on the menu bar... but i can't really put anything. the zotero bar won't show up...
any help ?
