Some folks have asked "Where is the <non-english language> installer for VMM already?"

It's in there. The "English" download includes all the languages VMM supports: English, German, Spanish, French, Italian, Japanese, Chinese simplified, Chinese traditional, and Korean.

So, for example, even tho the trial download refer-page says

"The Virtual Machine Manager trial software is available in the following languages:

English"

Please download and install and choose your supported language during setup.

Enjoy, genießen Sie, goce, appréciez, goda di, 楽しみなさい, 享用,즐기십시오.
