Regarding backup installers for MDK:

Despite the lack of specific download links for each language, as is usual even for multilingual installers, the "English" installer available right now includes all the new languages (and English too, of course).

You need to select the actual in-game language in the Options button at bottom left of the installer window (independently from the setup language you choose when running the installer).

MDK 2 on the other hand has individual downloads for each language.
