While Xtra-PC only officially supports English only, you can change the default language to other languages of your choice.

Most items in the Xtra-PC OS can be set to be displayed in a different language. Some are English only.

Some of the English only items are:
1. Initial set administrator password screen.
2. Initial setup wizard
3. Xtra-PC tools

Please see the attached pdf file that walks you through the steps of changing the default language from English to another language.
