Net Framework 1_1 setup has ended prematurely

[Jktyf]

Проблема: при установке Net Framework 1_1 процесс вроде бы проходит нормально, но в определенный момент начинается откат всех изменений (отмена регистрации dll и прочее); появляется сообщение: NET Framework 1.1 Setup has ended prematurely, If this persists, please contact Product Support.
Найденое по другим сайтам решение ("The problem usually is because a broken previous install. Rename %windir%\system32\mscoree.dll and re-install usually does the trick." - переименовать mscoree.dll) не дало результатов.
Система Xp Sp2, раньше на компе уже стоял Net Framework 1_1, Netовские программы работали (теперь не запускаются, теперь при их запуске появлятся сообщение " Ошибка при инициализации приложения (0xc0000005)").

А что в установочном логе?
