如何将所选语言用于卸载程序？

Question

我的.nsi具有以下配置：

#########################################################################
## Language Selection Dialog Settings

## Remember the installer language
!define MUI_LANGDLL_REGISTRY_ROOT "HKCU"
!define MUI_LANGDLL_REGISTRY_KEY "Software\${APP_COMPANY}\${APP_PRODUCT}"
!define MUI_LANGDLL_REGISTRY_VALUENAME "Installer Language"

## Languages (first language is the default language)
!insertmacro MUI_LANGUAGE "Portuguese"
!insertmacro MUI_LANGUAGE "English"
!insertmacro MUI_LANGUAGE "French"
!insertmacro MUI_LANGUAGE "Spanish"
!insertmacro MUI_LANGUAGE "Dutch"


## Language selection functions (for install and uninstall)
Function .onInit
  !insertmacro MUI_LANGDLL_DISPLAY
FunctionEnd

## Uninstaller Functions
Function un.onInit
   !insertmacro MUI_UNGETLANGUAGE
FunctionEnd

但是当我尝试卸载时，卸载程序每次都会显示语言对话框。

我遵循MUI2自述文件，但我不知道自己在做什么错。

Answer 1

MUI_LANGDLL_REGISTRY_ *指定的注册表值由MUI自动保存在MUI_PAGE_INSTFILES页面上。 如果您不使用此页面，则可以自己调用MUI_LANGDLL_SAVELANGUAGE宏，也可以手动编写$ LANGUAGE的值。

我建议您只使用MUI_PAGE_INSTFILES页面，以便一切为您服务：

!define APP_COMPANY "Foo"
!define APP_PRODUCT "Bar"
!include MUI2.nsh
InstallDir "$Temp\Test"
