Language error (Chinese instead of Italian) What means?

Want to change the language to chinese

I don't know if there's a language option for Chinese, but I have the European version of the game, here the language options are English, French, German, Italian, Spanish, Dutch, Swedish, Norwegian, Danish, and Portuguese.

These are the available languages within Just Cause 4

English, German, French, Italian, Spanish, Arabian, Brazilian, Portuguese, Russian, Korean (Interface Only), Chinese (simplified)(Interface Only), Chinese (Traditional)(Interface Only) and Polish (Interface Only).

There should be a a language setting in settings. I think you have to do it from the main menu however.

Ok. Maybe I don't understand. My info account has geographic area: Germany, but my xone language is Italian. My games are in Italian. What do you mean? Please explain me

Take a look at the third paragraph here:
www.techinasia.com/chinas-xbox-one-and-games-will-be-totally-region-locked

As Badger said, Chinese Xbox Ones and Xbox One Games are region locked, so you won't be able to play Chinese-purchased games on a non-Chinese Xbox One, and cannot play non-Chinese games on a Chinese Xbox One.

Also, just as a heads-up, be wary of the regional language settings - you have an Xbox One set to an English-speaking region, but that doesn't necessarily automatically mean that games bought from a non-English-speaking country will automatically play in
English. Some games are localized depending on the area where they are sold, so even if your Region's language is English, the game may still play in the native language (unless the game itself has a language control.)

As an example, on 360, some games had menu options to change the language, but on many EA games, the language of the game menu, subtitles, etc. were limited to the country from which it was purchased. I know some folks who purchased the Mass Effect series
from a store which didn't realize they were the Italian versions, and when they played them, there was no way to switch the language (despite the store trying really hard to help them, giving them the Italian words to look for in the menus to search for language
settings, etc.)

So, long story short, MOST games from most countries (including the US) are Region-free, but caveat emptor, because you never know if the game will be localized with no language menu.

anyone has this problem, MS not able to solve

Yea, I ended up downloading the chinese version as well, it was not mentioned in the store advert as well. I tried changing the language, and there was only simplified chinese, traditional chinese, and korean.

What gives Microsoft?!??

How can I get the english version instead?
