Install Files depending on the Installer Language

Hi
This may sounds stupid but Im looking for some example codes on how to install language specific files.
I modified the ModernUI Multilanguage Example and that works fine and to finally finish the installer i need to know how to install files depending on the installer language.
To be more specific i need this to install the correct configurations file for my program
My installer comes in English and German.
Thanks in advance 🙂

Like this:

!include "mui.nsh"
!include "logiclib.nsh"
!define INST_NAME "myMultyLang"
Name ${INST_NAME}
OutFile "${INST_NAME}.exe"
XPStyle on
ShowInstDetails show
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_LANGUAGE "Spanish" # 1034 or ${LANG_SPANISH}
!insertmacro MUI_LANGUAGE "English" # 1033 or ${LANG_ENGLISH}
!insertmacro MUI_LANGUAGE "German" # 1031 or ${LANG_GERMAN}
Function .onInit
!insertmacro MUI_LANGDLL_DISPLAY
FunctionEnd
