You need reinstall VS.

Language Pack Support in Visual Studio 2017 RC

Issue:

This release of Visual Studio supports only a single language pack for the user interface. You cannot install two languages for the user interface in the same instance of Visual Studio. In addition, you must select the language of Visual Studio during the initial install, and cannot change it during Modify.

Workaround:

These are known issues that will be fixed in an upcoming release. To change the language in this release, you can uninstall and reinstall Visual Studio.

You can only install a language pack at install time in VS 2017 RC. To install RC with a different language:

1. Open the Visual Studio Installer.
2. Find an addition under "Available" and click Install
3. Click on the "Language packs" tab and select a language

You can have multiple instances of VS 2017 side by side so this shouldn't interfere with your other installation.

Disclosure: I work on Visual Studio at Microsoft.

1. Go to Tools -> Options
2. Select International Settings in Environment and on the right side of a screen you should see a combo with the list of installed language packages. (so in my case Czech, English and same as on MS Windows )
3. Click on Ok

You have to restart Visual Studio to see the change...

If you are polish (and got polish language settings)

1. Narzędzia -> Opcje
2. Ustawienia międzynarodowe in Środowisko

Hope this helps! Have a great time in Poland!

This should solve it:

1. Open the Visual Studio Installer.
   
2. Click on the Modify Button.
   
3. Choose the Language Pack tab on top left.
   
4. Check the language you need and click on the Modify Button at bottom right.
