How to set the language of the Frontend?

After I update the ver.4.3.1, all interface change to japanese.
I fix the language of the Editor, but I have no ideal how to set in Frontend.
Anyone can help me,pls.

Currently, there is no UI to change the language in the frontend. You can manually set the language of any Unreal Engine program by modifying its *Engine.ini file. Add/find the Internationalization section, add/find the Culture key, set the value to the ISO 639 code of your desired language. You can find this file at /Engine/Programs/UnrealFrontend/Config/DefaultEngine.ini.


DefaultEngine.ini for English


DefaultEngine.ini for Japanese


Thank you very much

What about other UE versions of UnrealFrontend?
For example v4.12, directory tree seems different.
