I have an angular/electron app with NSIS Installer. How Can I set language in which this installer window appears? For example I want installation directory window to be in german instead of english. I could not find any documentation about this topic.
According to the Electron Builder documentation you should set installerLanguages
to "de_DE" in the nsis
key in your configuration.
If you want to use a fully custom NSIS script instead, it would just be:
!include MUI2.nsh
!insertmacro MUI_PAGE_DIRECTORY
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_LANGUAGE German
