Wubi не может установить Lubuntu 12.04 [дубликат]

Exception: Could not retrieve the required installation files

Это происходит каждый раз, когда Wubi завершает установку Lubuntu. Я знаю, что есть такие вопросы, за исключением того, что я не могу использовать USB-накопитель, достаточно большой для Lubuntu, и мой компьютер не будет работать с приводами CD / DVD.

Полный журнал слишком велик для вставки, но вот несколько последних строк.
