Internationalizing user messages in NSIS

Is there a way to internationalize the user messages in NSIS as we do in java ?

Something like to have file which will have all the key and value string defined. When needed in a different language we just replace this file which contains value string defined in the localized language, which is usually done by a translater.

Or doing the langString way is the only way to internationalize on NSIS?

Thanks in advance !!

Do you want to internationalize your NSIS installer, or your own application?

For the installer, you can load entire language lists using LoadLanguageFile. http://nsis.sourceforge.net/Docs/Chapter4.html#4.9.15

Or use !insertmacro MUI_LANGUAGE "English" etc for MUI installers.
