How to force to a certain language

I would like to force my installer to always be in German, regardless of the Windows language and such. What do I need to do to make all the standard interface elements German? I thought just adding this to the top of my installer script would fix it:

Function .onInit
StrCpy $LANGUAGE "1031"
FunctionEnd

However, the NSIS script compiler considers this okay, but my installer is still in English. What am I doing wrong here?

By the way, I found the value "1031" for German here. I also tried using the hex value given there: $0407.

You did not pass any code to find out the problem you have, Have you tried it this way:

;--------------------------------



OutFile languages.exe

XPStyle on

RequestExecutionLevel user



;--------------------------------

LoadLanguageFile "${NSISDIR}\Contrib\Language files\English.nlf"

LoadLanguageFile "${NSISDIR}\Contrib\Language files\German.nlf"





;--------------------------------

Section ""



SectionEnd



;--------------------------------

Function .onInit

  ;english

  ;StrCpy $LANGUAGE 1031



  ;german

  StrCpy $LANGUAGE 1033

FunctionEnd

if you're using MUI2, you can also use..

!insertmacro MUI_LANGUAGE "German"

..and call it a day - no need to touch the language bits yourself; it pretty much does what th_mi explained under the hood

Ah, that was easy! I did have to combine it with an include, but that was it:

!include "MUI2.nsh"

!insertmacro MUI_LANGUAGE "German"

Awesomesauce, thanks for the quick help!

if you don't want MUI or MUI2, just do a

LoadLanguageFile "${NSISDIR}\Contrib\Language files\German.nlf" 

and no other LoadLanguageFile...
