{% hint style="success" %}
Applications required

* **Game Launcher PRO Edition**

  {% endhint %}

### Add a new language in the code

1. In **Visual Studio Solution Explorer**, open *<mark style="color:purple;">**Localization.cs**</mark>* under **GameLauncherCore** project

{% hint style="info" %}
You can search for the ISOCode for your new language here: <https://www.andiamo.co.uk/resources/iso-language-codes/>
{% endhint %}

2. Duplicate the **SetLanguage\_EN\_US** function and change the name to your ISOCode

**Example:** *English (United Kingdom) | en-gb* \
We duplicated the ***SetLanguageEN\_US*** function and changed the name to ***SetLanguage\_EN\_GB***
