Question

要求1：我们的卸载程序必须只删除安装程序安装的特定文件夹中的文件（即安装后添加的任何文件必须保持不变）。

要求2：还需要卸载程序驻留在上述文件夹以外的特定位置。

我找到并尝试了高级卸载日志NSIS标题＆＃34;在这里找到： http://nsis.sourceforge.net/Advanced_Uninstall_Log_NSIS_Header

虽然高级卸载日志NSIS标头看起来非常有前景，（很好地满足要求1），但我无法确定是否可以使它也适用于要求2.

标头是否可以用于仅卸载已安装的文件，并且可以从除创建.dat文件的目录以外的其他目录调用？

提前致谢。

Answer 1

在AdvUninstLog.nsh中，您应该注释掉与UNINST_EXE相关的任何内容，尤其是WriteUninstaller行。我不确定你是否想要.dat和卸载程序在同一目录中，所以我使用单独的目录只是为了安全起见。

...
!include AdvUninstLog.nsh
!insertmacro UNATTENDED_UNINSTALL
Page Directory 
Page InstFiles

Function .onInit

    !insertmacro UNINSTALL.LOG_PREPARE_INSTALL

FunctionEnd


Function .onInstSuccess

    !insertmacro UNINSTALL.LOG_UPDATE_INSTALL

FunctionEnd

Section "Main Application"

    SetOutPath "$InstDir\foo"
    WriteUninstaller "$InstDir\foo\uninst.exe"

    SetOutPath "$InstDir\data"
    !insertmacro UNINSTALL.LOG_OPEN_INSTALL
    File /r "${NSISDIR}\Plugins\*" ; "random" files
    !insertmacro UNINSTALL.LOG_CLOSE_INSTALL

    WriteRegStr ${INSTDIR_REG_ROOT} "${INSTDIR_REG_KEY}" "InstallDir" "$InstDir"
    WriteRegStr ${INSTDIR_REG_ROOT} "${INSTDIR_REG_KEY}" "DisplayName" "${APP_NAME}"
    WriteRegStr ${INSTDIR_REG_ROOT} "${INSTDIR_REG_KEY}" "UninstallString" '"$InstDir\foo\uninst.exe"'

    ; Because the UNINSTALL.LOG_UPDATE_INSTALL macro is responsible for writing the .dat
    ; it is important to set $InstDir to the directory you want it to be located in.
    ; This must be done as the last step in your last Section so that $InstDir has
    ; the correct path when .onInstSuccess is executed.
    SetOutPath "$InstDir\bar" ; Make sure the directory exists
    StrCpy $InstDir "$InstDir\bar"

SectionEnd

Section UnInstall

    ; In the uninstaller the initial value of $InstDir is the folder the uninstaller .exe is in.
    ; In this example I put it in a subfolder so we need to get the root of our install:
    GetFullPathname $InstDir "$InstDir\..\"

    ; This is important, it changes $InstDir to the folder where the .dat is located.
    Push $InstDir ; Save
    StrCpy $InstDir "$InstDir\bar" 
    !insertmacro UNINSTALL.LOG_BEGIN_UNINSTALL
    Pop $InstDir ; Restore

    !insertmacro UNINSTALL.LOG_UNINSTALL "$INSTDIR\data"
    !insertmacro UNINSTALL.LOG_END_UNINSTALL
    DeleteRegKey /ifempty ${INSTDIR_REG_ROOT} "${INSTDIR_REG_KEY}"

    ; Because the uninstaller and the .dat were located in their own (unlogged) folders
    ; we need to manually delete them:
    Delete "$INSTDIR\foo\uninst.exe"
    RMDir "$INSTDIR\foo"
    Delete "$INSTDIR\bar\${UNINSTALL_LOG}.dat"
    RMDir "$INSTDIR\bar"

    RMDir "$INSTDIR"
